There are two safe ways of processing food, the boiling water bath method and the pressure canner method: The boiling water bath method is safe for tomatoes, fruits, jams, jellies, pickles and other preserves. Pressure canning is the only safe method of preserving vegetables, meats, poultry and seafood.
- Prepare your food for canning as indicated by a recipe.
- Sterilize jars, lids and rings by boiling in water for 10 minutes.
- Fill the jars with hot food and seal them with a lid and a ring.
- Fill a pot half full of water and heat to 180 degrees.
Place lids on jars, screw on rings and lower jars back into the pot of boiling water. The water should cover the jars; if not, add more. Boil jars for 10 minutes. Transfer jars to a folded towel and allow to cool for 12 hours; you should hear them making a pinging sound as they seal.
Wash the jars, lids, and screw bands in hot, soapy water, making sure to rinse well. 2. Place the jars upright on a wire rack in a large pot, fill pot with hot water until the jars are submerged, and bring the water to a boil. Boil for 10 minutes, turn off the heat, and leave jars in the water.
Pressure canning is the only safe method of preserving vegetables, meats, poultry and seafood. Jars of
food are placed in 2 to 3 inches of water in a special
pressure cooker which is heated to a temperature of at least 240° F.
The low acidic foods include:
- meats.
- seafood.
- poultry.
- dairy products.
- all vegetables.
The definition of canning is the act of preserving food in jars, or firing someone. When you cut up cucumbers and make them into pickles that you preserve in a jar to eat throughout the winter, this is an example of canning.
In general, 3 inches of hot water into the canner. Too much water is unlikely to cause harm, but too little could boil dry and that would be a major problem. To prevent water stains on jars, add 2 tablespoons white vinegar to water in canner. Always use canning rack.
Boiling water bath canning is the easiest way to make shelf-stable jams and pickles right in your own home. It's important to note that only high-acid foods can be preserved by water bath canning. This includes most fruit preserves, including jams, jellies, and fruit canned in syrup, and many pickles.
Required canning equipment
- Canning jars, lids and rims. Canning jars, commonly known as mason jars, are created specifically for canning.
- Water bath canner. (or large pot with a lid, and a rack)
- Jar lifter.
- Dutch oven or large stock pot.
- A stir stick or chopstick.
- A kitchen timer.
- Canning funnel.
- Pectin.
Canning is not difficult, at least not in the sense of needing a special skill set. When it gets right down to it, canning is simply a matter of immersing hot jars into boiling water long enough to suck out all the air, thereby sealing the jars. That's it!
Here are the best Mason jars you can buy:
- Best Mason jars overall: Ball Mason jars.
- Best with smooth sides: Anchor Hocking Mason jars.
- Best with wide mouths: Kerr wide-mouth Mason jars.
- Best with bail tops: Bormioli Rocco bail top Mason jars.
- Best with handles: Libbey handled drinking Mason jars.
Yes for low acid foods, you'll need a pressure canner. Look at the All American canners. It's worth the money. I also like doing my tomatoes in the pressure canner because I can do up to 16 pint jars at a time and I don't have to heat up the kitchen for as long as I would if I used my BWB.
Shelf Life.
As a general rule, unopened home canned foods have a shelf life of one year and should be used before two years. Commercially canned foods should retain their best quality until the expiration code date on the can. This date is usually 2-5 years from the manufacture date.- Prepare your food for canning as indicated by a recipe.
- Sterilize jars, lids and rings by boiling in water for 10 minutes. Remove the jars, lids and rings one at a time for filling.
- Fill the jars with hot food and seal them with a lid and a ring.

Many people think sealing jelly jars with paraffin (baker's wax, canning wax) to be old fashioned. It is still, however, a viable canning method for short time periods. Paraffin sealed jellies should be used within a couple of months.
Over-tightening bands can prevent air from venting out of the jars, resulting in buckled lids or seal failure. After processing, bands may appear to have loosened. You can reuse the jar itself and even the bands, but you can never reuse the Mason jar lid—for canning, that is.
10 Foods You Should Never Can at Home
- Milk. Milk, or items containing milk, aren't recommended for home-canning.
- Lard. With the high density and fat content, lard is just not a good item to can.
- Refried Beans. There are some recipes out there for canning refried beans but they can be dangerous.
- Pickled Eggs.
- Butter or Cream.
- Cornstarch.
- Flour.
- Nuts and Cashews.
Spam, canned chicken, corn beef, canned ham, and tuna can last from 2 to 5 years after the can's printed date, so long that it's stored in ideal conditions.
Home canning is affordable and trendy, but can be deadly if proper safety precautions are not taken during the canning process. From 1996 to 2014, 30 percent of foodborne botulism outbreaks reported to the Centers for Disease Control and Prevention were from home-canned vegetables.

You cannot tell by looking at a jar of home canned food if it is safe, just because it's sealed, does not mean that it's safe. A seal just means that you had vacuum action from it getting hot and cooling down. A sealed jar is in no way an indication that the food is safe or not.
Most fruits and berries are relatively high in acidity, so they're good candidates for canning. Decide among them based on texture and sturdiness. Large fruits such as apples, pears, peaches, plums and nectarines all can well. So do sturdy berries, such as strawberries and blueberries.
Top 10 Easiest Foods to Can
- Tomatoes. Tomatoes can easily be canned in a water-bath canner, as long as you add extra lemon juice to increase the acidity of the mixture.
- Cucumbers. Most people prefer to can cucumbers as dill or sweet and sour (also known as bread and butter) pickles.
- Beans.
- Corn.
- Stock.
- Fruit.
- Squash.
- Leafy Greens.
If you're planning on canning, you can reuse your purpose-made glass jars and screw bands, as long as they're in good condition. The metal snap lids, on the other hand, are made to be used once. And since the quality of the seal is essential to preserving what's inside the jar, they should not be reused.

This can be done by placing a nonmetallic spatula or plastic knife inside the jar between the food and the side of the jar. Gently press the spatula against the food to create a path for trapped air to escape. Repeat several times around the inside of the jar.

Here's how to sterilize canning jars:
- Place empty jars right side up on the rack in a boiling-water canner.
- Fill the canner and jars with hot (not boiling) water to one inch above the tops of the jars.
- Bring to a boil and boil 10 minutes.
- Carefully remove hot, sterilized jars one at a time and drain.
- They will be hot!
