Can I buy mason jars by mail order? (i.e. Order Online)

Due to the special handling and high postage costs required to deliver cases of glass jars without breakage, Bernardin mason jars are not offered in our mail order selection. Selected mass merchandisers, hardware and grocery stores across Canada, sell a selection of BERNARDIN® Mason Jars year-round. If you don't see them in the store, ask the store manager. If the item is listed in the store's central warehouse, the manager can order it in for you.

Four-packs of BERNARDIN® Collection Elite® mason jar storage pots and lids are available in the Order OnLine section of the website.

Can vegetables be canned safely without adding salt?

Yes, vegetables can be home canned safely without salt. The measured quantity of salt indicated in most recipes is intended for taste and seasoning. The quantity is too small to control food spoilage. If desired, simply omit salt or reduce to taste. Do not omit or reduce salt from pickled foods or seafood.

Does Bernardin have a factory outlet store?

No, Bernardin does not operate a factory outlet store. Direct sales to consumers are not made at the company´s headquarters in Toronto.

Grocery and general merchandise stores across Canada continue to be the most cost efficient source of Bernardin home canning products. We recognise, however, that retailers limited display space makes some of our products difficult to locate in some areas, year-round. Thus a selection of home canning supplies and accessories are available via mail order. Clicking ORDER ONLINE presents this selecton.

How do different canning methods effect the safety of home canned foods?

There are no safe short-cuts in home canning. Heat processing all high acid foods in a boiling water canner and low acid foods in a pressure canner--for the appropriate time for the food and jar size--are the only currently approved methods for safe home canning.

There is no substitute for adequate heat treatment. Some people may experience "good luck" with outdated methods...and then one year everything spoils! Each growing season is different. Heat-resistant bacteria are not necessarily present in every piece of produce. IF these organisms are absent...and that's a big IF...under-processed foods might keep. When they are present, the food spoils. Be safe rather than sorry. Always assume these microorganisms are present. Follow current, tested practices, such as those recommended on this site, that use the equipment and supplies available to you today.

Certain home canning methods and techniques, once thought to offer success, have been shown to be faulty, unsafe and potentially dangerous. These include:

1) CANNING WITH RUBBER RINGS & GLASS LIDS

Due to their high failure rate, the use of jars that utilize glass caps and rubber rings are not recommended for safe home canning today. Reference: Complete Guide to Home Canning and Preserving, Second Revised Edition, U.S. Department of Agriculture, 1999, p 10 and 11. This publication further states the same with regard to jars with wire bails and glass caps, one-piece zinc porcelain lined caps and flat rubber rings.

2) PARAFFIN WAX

Paraffin wax is NOT recommended for safe food preservation for a number of reasons.

NOTE: Paraffin wax is a flammable material that can be dangerous, especially when handled by inexperienced cooks.

Melted paraffin shrinks as it solidifies. Liquefied paraffin covers soft spreads spreading to the jar rim, but as it cools and hardens, paraffin shrinks away from the glass enough to allow air to come in contact with the food leading to the development of molds. Although it may appear to be solid, hardened paraffin wax can have microscopic pinholes running through it. Thus air can come in contact with the food, which can lead to the development of molds.

It was once presumed that mold growth on jellied products could be removed (skimmed off) and the product below would be safe to eat. However, research has shown that mold growth may produce mycotoxins, that can be very harmful to human health. Mycotoxins can migrate like invisible threads through the food to the bottom of the jar. Thus, skimming the surface mold will not remove mycotoxins.

The only safe way to eliminate or prevent mycotoxins is to place freshly-made soft spreads in mason jars with Bernardin two-piece home canning SNAP LID® closures followed by heat processing for the recommended method and time for the product and jar size. Heat processing vents air from the headspace, heats container and contents to inactivate food spoilage organisms and creates an airtight vacuum seal as the product cools

3) OPEN-KETTLE CANNING

Open-kettle canning is not safe and is not recommended for food preservation. Open-kettle canning involves cooking the food in an open saucepan. The hot food is then put into jars and the lids are quickly put in place. This method "hopes" that a proper seal will be achieved as the food cools.

Regardless of the duration or heat intensity of the cooking period, the open-kettle method is not safe because the filled jars of food are not heated to and maintained at temperatures necessary to destroy spoilage microorganisms and assure strong vacuum seals. The open-kettle method omits essential heat processing necessary to drive the air from the jar to create a vacuum seal. The lid may appear to seal, but later may unseal due to a low vacuum. Or, microorganisms left in the food may cause spoilage. This spoilage produces gases, which in turn increase pressure inside the jar. The increased pressure may force the lid to release.

Foods ferment when open-kettle canning does not destroy yeasts, or permits them to enter the jar as it is filled and before it is sealed. Simply getting lids to curve downward on jars will not, in itself, prevent food from spoiling. The only successful way to create an airtight vacuum seal and destroy spoilage microorganisms is to heat process all filled jars by a method and time, appropriate for the type of food and jar size.

4) OVEN CANNING

Not only is it unsafe, oven-canning can be extremely hazardous. Regardless of the brand of oven, jar, cap or lid you use, jars can break or explode due to temperature fluctuations when the oven door is opened. When you preserve food, it is important to know and control temperature. Oven temperatures vary according to accuracy of the oven regulator and how heat circulates. Also, dry heat penetrates food jars very slowly. Moreover, the temperature of the food inside the jar is not heated sufficiently to destroy microorganisms.

5) STEAM CANNING

Do not confuse steam canning with pressure canning. Steam canning places jars of food on a rack in a covered, shallow pan. As the water in the shallow pan boils, steam is circulated around the filled jars. Steam in this device is not pressurized. These canners do not create a steady flow of steam nor maintain an even temperature. It is impossible to know if the heat has penetrated the food properly. The heat processing times given in recipes on this site are safe for processing foods in a boiling water canner or pressure canner as specified. Do not use these processing times for a steam canner as safe processing times have not been established for this method.

What are the Instructions for Heat Processing?

Foods are divided into two groups when home canning: High Acid and Low Acid. This is due to the different types of spoilage micro-organisms they may contain. Each group requires a specific heat processing method to effectively destroy these micro-organisms and avoid spoilage while filled jars are in storage.

• High Acid Foods: jams, jellies, fruits, tomatoes with added acid, pickled products including dill pickles, relishes and chutneys.

• Low Acid Foods: vegetables, meat, poultry, game, seafood, tomatoes without added acid and most tomato-based products such as spaghetti sauces.

High Acid Foods: These foods require the temperature of boiling water (212ºF/100ºC) to destroy yeast and mould. This is done in a boiling water canner with a rack on the bottom. Cover the filled jars with 1 to 2 inches (2 to 5 cm) water and bring to a boil. Start timing the heat processing only when water boils. Times vary depending on jar size, food density and chemical make-up. Never use a recipe that does not specify a heat processing time.

Low Acid Foods: These foods require a temperature of 240ºF (116ºC) to destroy harmful bacteria such as Clostridium botulinum (Botulism). This temperature, higher than that of boiling water, can only be achieved in home kitchens with a pressure canner. Boiling water alone is not enough to kill bacteria that live in low acid food, and will actually promote its growth. Never use a recipe for low acid food that does not give instructions on how to heat process in a pressure canner. Also, refer to your pressure canner instruction manual.

*Only use home canning recipes from reliable sources, such as Bernardin. Never use a recipe that does not give a heat processing time and method for the food that you are preserving.

How to Remake cooked jam/jelly using powdered fruit pectin

1) Measure unset jam/jelly to be remade.

2) For each 1 cup (250 ml) product, measure:

2 tbsp (30 ml) granulated sugar,

1 tbsp (15 ml) water and

1 tsp (7 ml) BERNARDIN® Fruit Pectin.

3) In a large, deep stainless steel saucepan, whisk fruit pectin into water. Stirring constantly to prevent scorching, bring to a boil. Stir in the measured jam and sugar.

4) Stirring constantly over high heat, bring to a full rolling boil; boil hard 30 seconds. Remove from heat; skim foam, if necessary.

5) Ladle into hot sterilized jars, leaving 1/4 inch (0.5 cm) headspace. Remove air bubbles. Wipe jar rim removing any stickiness. Centre new SNAP LIDS® on jars; apply screw bands securely until fingertip tight. Heat process 10 minutes in boiling water canner.

How do I know if a home canning recipe from friends/family is safe to use?

Be sure the recipe complies with up-to-date guidelines that include proper heat processing of all filled jars using the appropriate method and time for the type of food, jars and lids available today.

Home canning books or recipes considered to be family heirlooms or treasures, may not always be safe to use. In 1989, the United States Department of Agriculture (USDA) updated their home canning guidelines based on safety and quality. Therefore, a home canning book or recipe that was published before 1989 may be outdated and could affect the safety and quality of your home canned foods.

The BERNARDIN® Guide to Home Preserving, BERNARDIN® Complete Book on Home Preserving as well as other books available in the Reference Library of Order OnLine offer up-to-date information and recipes.

How do I prepare my mason jars and SNAP LID® prior to use?

Visually inspect mason jars for nicks, cracks, uneven rims or sharp edges that may prevent sealing or cause breakage. Check screw bands for proper fit on your mason jars and be sure SNAP LID® are new (previously unused) and scratch-free.

Wash jars and lids in hot, soapy water; rinse well. Place required number of clean mason jars on a rack in a canner or large saucepan.

If using a boiling water canner; cover jars with water and heat water to a simmer (180°F/82°C). Keep jars hot until used.

If using a pressure canner, place clean jars in canner, add water to 3-inch depth (7.5 cm) and heat to a simmer (180°F/82°C), Leave jars in hot water until used.

(Note, if packing jars with chilled fish, do not preheat jars or water prior to filling jars. When mason jars are filled and pressure canner is filled, add room temperature water to depth recommended by pressure canner manufacturer.)

Heat processing time recommendations for jams and jellies was been increased from 5 minutes to 10 minutes in 2003, thus eliminating the need to pre-sterilize mason jars before filling. Tests have shown that increasing the processing time does not adversely affect the product. If you choose to continue to use high acid recipes that require less than 10 minutes heat processing time, mason jars should be boiled 10 minutes, at altitudes up to 1,000 ft (305 m), prior to filling and the subsequent shorter than 10-minute heat processing time.

"Boiling lids" prior to placement on jars is no longer required for home canning. This recommendation has been changed to "Bring SNAP LID® to a boal and leave in hot water until ready to use. In the past, the recommendation was to "boil SNAP LIDS® five minutes" before placing them on filled jars. Extensive testing by Bernardin's technologists revealed that boiling the lids too long, combined with overly tight application of the screw bands could lead to seal failure. SNAP LID® must be hot when placed on hot jars of hot food, whereas screw bands should be room temperature. Tighten screw bands securely & firmly until resistance is met - don't overtighten. Heat processing ALL filled jars is still a necessity for safe home canned foods.

Screw bands require no preparation and are much easier to handle if left at room temperature. Apply screw bands evenly and firmly until resistance is met. Don't overtighten as this prevents venting - air escaping - during heat processing.

* Heat processing all filled jars is still a necessity for safe home canning.

How do I reduce the quantity of sugar in jam or jelly recipes?

When preparing jams or jellies with dry or liquid fruit pectins, reducing the quantity of sugar from that recommended in the recipe can cause gel failure. Consumers with special dietary needs may wish to use a special product, BERNARDIN® No Sugar Needed Fruit Pectin, which gels fruit mixtures with no added sugar. Such fruit spreads are sweetened exclusively by fruit's natural sweetness. The sweetness of fruit spreads made with this No Sugar Needed pectin can be enhanced with artificial sweeteners or a small quantity of corn syrup, honey or up to 3 cups of granulated sugar.

The quantity of sugar in a long boil jam recipe may be reduced at the maker's discretion. However, the product will need to be cooked longer to reduce liquids and concentrate the natural sugars from the fruit used. In many cases, this lengthened cooking will result in a product with a carmelized flavour and considerably lower yield than similar quantities of fruit prepared with added pectin. Although long boil fruit spread recipes appear to use less sugar, by the time they are cooked down the sugar concentration is likely to be very close to added-pectin recipes that start with a greater quantity of added sugar.

Jellies require a delicate balance of sugar, fruit juice and acid. For ultimate jelly-making success, start with a tried and true jelly recipe and use ingredients in the specified quantities.

How tightly should screw bands be applied?

Apply screw bands securely until fingertip tight. Center the prepared SNAP LID® on the jar. Then, using just your fingers, screw the band down evenly until you meet a point of resistance. Do not overtighten bands by using the full force of your hand or a utensil to tighten the band.

After processing, bands may appear to have loosened. This is natural. Do not retighten bands after processing. Let jars stand undisturbed 24 hours.

Overtightening bands prevents venting of excess air from the jar during heat processing. Jars that do not vent properly do not seal securely. Screw bands that are applied too tightly can cause lids to buckle. Buckling leads to seal failure.

If home canned foods have frozen during storage, are they safe to eat?

If the jar of food was processed according to current home canning recommendations , and the jar is still vacuum sealed, the food should be safe to eat. Examine the jar closely, freezing can cause damage to the vacuum seal or jar breakage. Home canned food that has been frozen during storage may by less desirable due to changes in texture, flavour, nutritional value and colour.

Jar and Lid Prep

Preliminary: Visually inspect mason jars for nicks, cracks, uneven rims or sharp edges that may prevent sealing or cause breakage. Do not use these jars. Check screw bands for proper fit on your mason jars and be sure the enamel surface of SNAP LIDS® closure is scratch-free. Wash jars and lids in hot, soapy water; rinse well.

Canning: Place clean mason jars on a rack in a boiling water canner; cover jars with water and heat to a simmer (180°F/82°C). Keep hot until use. Set screw bands aside; heat lids in hot water, not boiling (180°F/82°C). Keep jars and lids hot until ready to use.

Notes:

• Screw bands do not have to boiled or heated because they do not come in contact with the food. Screw bands may be re-used. Discard any rusted, scratched or dented bands.

• SNAP LID® closures are designed for single-use only. Once a seal is formed, the indent in the red plastisol is permanent and may prevent another seal from forming. SNAP LID® closures that were placed in hot water but not needed, may be dried and used for your next canning project.

What causes food/liquid to leak out of jars after and/or during heat processing?

Loss of liquid from a jar of food is called "siphoning". It can be caused by: too little headspace failure to keep jars upright at all times removal of jars from processing a boiling water canner too quickly (before boil has subsided)too little water above the jars during boiling water processing fluctuating pressure in a pressure canner.

What causes seal failure or lids to seal then unseal?

The use of up-to-date home canning utensils and supplies, following the manufacturer's recommended lid application techniques and heat processing steps are all essential for sealing success with home canning two-piece metal lids.

The most common causes of seal failure are: Insufficient heat processing of filled jars. When filled jars are not heat processed and/or when the heat processing method or time are inadequate for the type of food and jar size, excess air is not vented from the jars and microorganisms that cause food spoilage are not inactivated. Initially, some lids may appear to seal. i.e. curve downward. However, these same lids may unseal during shelf storage. The seal failure at that time is caused by one of two reasons:

1) Very low vacuum was created initially. Low vacuums do not hold over time.

2) Due to inadequate heat processing, food begins to spoil inside the jar. This spoilage produces gases that force the lid to release. All filled jars, regardless of their content, must be heat processed by an appropriate method and time for safe, shelf-stable storage.

Over-tightening of screw bands. Overtightening screw bands prevents venting. Apply screw bands securely, until fingertip tight. Note: Applying screw bands very tightly, then backing them off a quarter turn is an outdated method that does not work successfully with BERNARDIN® SNAP LID®.

Re-tightening or tampering with screw bands immediately after processing before food is thoroughly cooled. Allow jars to cool undisturbed for 24 hours.

Incorrect headspace or failure to remove air bubbles before placement of the SNAP LID®.

Failure to soften sealing compound on SNAP LID® prior to use. Bring SNAP LIDS® to a boil and let stand in hot water until ready to use.

Reuse of single-use SNAP LID® or use of commercial food glass jars.

Use of mason jars with nicks, cracks or chips in the sealing edge or neck rim.Failure to clean the rim of the filled jar before applying the lid and/or rapid changes in processing temperatures that cause liquid to siphon from jar. Food, grease or seeds lodged between the jar rim and sealing compound can prevent the formation of airtight seals.

Careless or inappropriate handling of jars and lids before and after processing. i.e. inverting jars after filling or processing.

What should I do if a lid doesn't seal?

If a lid does not seal within 24 hours, the product must be:

Reprocessed immediately

Stored in the refrigerator and used within a few days

Placed in a proper freezer container and frozen.

To reprocess a product, remove the lid and check the sealing surface of the jar for tiny nicks or imperfections. If glass is damaged, replace the jar. If the product was packed hot originally, empty the jar and reheat the food. Pack the food into a clean, hot jar. (If processing time is less than 10 minutes, sterilize the jar before filling.) Boil a new SNAP LIDS® 5 minutes, place it on the jar and apply the screw band securely, until fingertip tight. Reprocess the product using the canning method and full processing time recommended by an up-to-date reliable home canning resource.

Where should home canned foods be stored?

Store home canned foods in a cool, dry draft-free place that is as dark as possible.

The best temperature range for home canned food storage is 50° to 70°F (10° to 21°C). Food stored at temperatures higher than 70°F (21°C), may lose some of its nourishing qualities. Freezing can cause the contents of a jar to expand which in turn can break the seal or the jar.

A dark storage area is preferred. Light hastens oxidation and destroys certain vitamins. It can also cause certain foods to fade in colour. Placing jars in cupboards or boxes protects them from light. Avoid damp storage areas as they can cause lids to corrode.

Factors that can contribute to soft pickles include:

Use of vinegar with an acidity level less than 5%
Pickles that are not processed or not processed long enough in a boiling water canner to destroy spoilage microorganisms
Variety and quality (freshness) of the cucumbers used
Improper storage or handling of cucumbers before pickling
Cucumbers were not completely covered with liquid when packed in the jar

IN FERMENTED PICKLES
Brine that was too weak when fermenting cucumbers
Cucumbers not completely covered with brine while fermenting
Scum not removed from top of brine while fermenting
Note: Heat processing does not, in itself, cause soft pickles. Heat processing is essential to create a strong vacuum seal that allows pickles to be stored safely at room temperature.

How do I use a Boiling Water Canner?

A boiling water canner is a large deep pot with a tight fitting lid and a rack to lift jars off direct heat. The pot must be deep enough to cover jars with 1 to 2 inches (3-5 cm) water.

Only high acid foods -- jams, fruits, tomatoes with added acid, pickles (including relish, chutney) -- can be processed safely in a boiling water canner.

Heating jars in water is the ONLY way to safely sterilise jars and heat process high acid food.

Tip: Turn any large, deep pot into a boiling water canner and tie screw bands together to make a rack.

1. PREPARING YOUR MASON JARS:Visually inspect mason jars for nicks, cracks, uneven rims or sharp edges; do not use if the jars are damaged.

Wash jars and lids in hot soapy water; rinse well.

Place mason jars on a rack in a boiling water canner.

Fill canner with enough water to cover jars.

For all recipes, heat water to a simmer (180°F/82°C).

Allow jars to remain in hot water until needed.

Lids: Set screw bands aside; heat lids in hot water, not boiling (180°F/82°C); keep hot until used.

FILLING YOUR MASON JARS:

Fill one jar at a time.

Ladle or pour prepared food product into jar, leaving proper ‘headspace’ as indicated in recipe.

Remove air bubbles by sliding a non-metallic utensil between jar and food; readjust headspace if necessary.

Wipe jar rim, removing any food residue.Centre hot lid on clean jar rim. Screw band down until resistance is met, then increase to fingertip tight. Return filled jar to rack in canner. Repeat for remaining jars and food.

2) HEAT PROCESSING FILLED MASON JARS:

In home canning terms, “processing” means heating filled jars at the temperature and time required to destroy spoilage microorganisms, inactivate enzymes and vent excess air from the jar. As the filled jar is heated, headspace pressure increases until air is vented from the jar. After processing, the atmospheric pressure outside the jar is greater than inside due to this "venting". This pressure difference causes the lid to be pushed down onto the jar, resulting in a true vacuum seal. This seal prevents microorganisms and air from entering and contaminating the food.

There are only two “heat processing” techniques recommended for safe home canning.

The acidity of the food you are home canning dictates the processing method. Heat processing methods are not interchangeable.

BOILING WATER PROCESSING IS USED FOR HIGH ACID FOODS.

High Acid Foods include jams, jellies and other soft spreads, fruits and fruit juices, pickled fruits and vegetables, relishes, chutney, salsa, tomatoes with added acid and high acid fruit-tomato sauces and condiments. This technique requires filled, closed jars of food to be placed on a rack, immersed in water, brought to a rolling boil and boiled steadily for the “processing time”. The type of food and jar size determines this time.

PRESSURE CANNING OR PROCESSING IS REQUIRED FOR ALL LOW ACID FOODS

Low Acid Foods include all vegetables, meat and game, poultry, fish, seafood, soups, stews, tomato-vegetable sauces and tomato-meat sauces.

Because the steam inside the canner is pressurized, its temperature exceeds the boiling point of water--212°F (100°C). Therefore, filled jars can be heated to 240°F (116°C). The food is held at this pressure and temperature for the “processing time” specified in up-to-date, tested home canning recipes. These times and temperatures have been established to destroy all bacteria, their spores and the toxins they can produce. In low acid foods, failure to destroy the bacterium, Clostridium botulinum can cause botulism, a deadly form of food poisoning. Boiling water canners are not appropriate for safe processing of low acid foods.

Botulism is a deadly disease caused by ingesting the toxic substance produced by the bacterium Clostridium botulinum (C. botulinum). This is a concern with improperly canned food.

Background on BOTULISM:

Spores of the bacterium C. botulinum are found everywhere in nature. In normal cases, the spores are of no harm to us. However, in certain environments, the spores produce vegetative cells. It is these cells that produce the deadly toxin. The following circumstances are favourable for C. botulinum spores to produce toxic vegetative cells:a low acid environment (>4.6), such as vegetables and meats

the absence of air, such as a sealed mason jar a moist environment, such as food

The environment described above is identical to a jar of canned low acid food. Low acid food includes: all vegetables (not pickles), meat, fish, seafood, game and tomatoes without added acid.

The Solution to BOTULISM:

Low acid foods may still be safely home canned. Botulism spores can be destroyed by a temperature of 116ºC (240ºF). This high temperature can only be achieved by the use of pressure in a pressure canner. Home canning recipes for some common low acid foods are available from BERNARDIN®. These provide instructions and the proper processing times for that food.

Note: Botulism is a frightening disease, not only because it may cause death, but because it is very difficult to detect in home canned food. C. botulinum has no smell and does not produce a gas. It is crucial that all low acid food be canned in a pressure canner for the appropriate time and pressure recommended.

High acid food includes jams, jellies, fruits, pickles, relishes, salsas and tomatoes with added acid. These foods have no risk of botulism, if properly prepared, due to their natural acidity.

Why does Fruit Float?

Floatation occurs frequently and naturally in canned fruits and vegetables. Although it may be visually unappealing, it is not dangerous by any means. There are, however, some steps that you can take to keep your home canned food looking as good as it taste.

TO AVOID FLOATING FRUITS AND VEGETABLES, YOU SHOULD:

Use fully ripe, unblemished produce. Do not use overripe produce.

Pack produce firmly into jars. Straight-sided jars allow produce to float. Using jars with “shoulders” helps hold food down in the jars.

Avoid too heavy of a syrup. Decrease the sugar concentration the next time if you feel that it has contributed to floatation.

Process only for the time indicated in recipe. Over-processing will cook the natural pectin in fruits unnecessarily and damage it. Pectin helps fruits hold their shape.Process foods using a boiling water canner unless a pressure canner is indicated in the recipe. Pressure canning high acid foods may over-cook them and lead to more floatation.

Hot pack your foods. Heat your fruits or vegetables in their canning liquid before packing in jars to remove air within the tissues. If packed cold, this air will contribute to floatation and discolouration. NOTE: Do not pre-heat pickles or citrus fruit before filling jars.

Take care not to damage the produce before canning. This may activate enzymes that destroy the natural pectin, leading to floatation.

Can I use Oil in Home Canning?

It is not recommended to use large amounts of oil in home canning recipes. Grocery stores carry commercial items such as pesto, garlic in oil and flavoured oils, but these cannot safely be canned in your home. Most home canning recipes using oil are intended for short-term refrigerator storage only.

WHY? Because of the harmful bacteria Clostridium botulinum (C. botulinum), the cause of botulism. C. botulinum produces a deadly toxin when in an environment that is:

• low acid (pH > 4.6)

• anaerobic, or absent of oxygen 

• room temperature

• moist

These conditions are identical to those inside a home canned mason jar containing oil. Home canning with oils may promote the growth of C. botulinum, causing food poisoning to anyone who consumes it, possibly resulting in death. Instead, make your recipe using oil and store it in the refrigerator for up to three weeks. Use fresh, clean ingredients and utensils when making your recipe and discard any leftovers after 3 weeks.

For more information, visit www.foodsafety.ufl.edu/consumer/or/or001.htm

What are the Pressure Canner Styles?

Weighted gauge pressure canners have small weights that regulate pressure at 5, 10 or 15 lbs of pressure. When the recommended pressure is reached, the weight begins to jiggle or rock. Each time the weight jiggles a small amount of steam is exhausted in order to maintain a constant pressure.

Dial gauge pressure canners have an exterior dial that measures the internal pressure very precisely. In order to maintain accuracy and prevent under processing, the dial gauge should be checked annually.

Sealing gaskets: Examine the sealing gasket on either style of canner annually to check for cracks, tears, stretching or drying out. Old sealing gaskets allow steam to escape from the edge of the canner lid and prevent the proper build-up of pressure.

PREPARING YOUR MASON JARS:

Visually inspect mason jars for nicks, cracks uneven rims or sharp edges.

Wash jars and lids in hot soapy water; rinse well.

Place mason jars on the rack in your pressure canner.

Fill canner with 2 to 3 inches (5 to 8 cm) of water, bring water to a simmer to thoroughly heat mason jars prior to filling.

Allow jars to remain in hot water until required.

FILLING MASON JARS: Fill one jar at a time.

Pack prepared food product into jar leaving proper ‘headspace’ as indicated in recipe.

Remove air bubbles by sliding a non-metallic utensil between jar and food; readjust headspace if necessary.

Wipe jar rim removing any food residue.

Centre hot lid on clean jar rim. Screw band down until resistance is met, then increase to fingertip tight. Return filled jar to rack in canner ensuring jars are covered by water.

HEAT PROCESSING FILLED MASON JARS:

When all jars are filled and canner is full, lock canner lid in place, leaving vent open. Turn stove on high heat. Allow steam to escape steadily for 10 minutes.

Close the vent using the weight or method described for your canner. Gradually reduce the heat to achieve and maintain the recommended pressure. Regulate heat only with gradual changes to heat level.

Once canner reaches specified pressure for your altitude, begin counting ‘heat processing’ time.

Note: Pressure cookers are generally smaller in size and capacity than pressure canners. Since pressure canning heat processing time is calculated to included both the heat up and cool down times of a pressure canner, it is essential to always use a proper “pressure canner” specially designated for processing low acid foods.
