Typically called a "water bath canner" it consists of a large cauldron style pan with a removable rack to hold canning jars. Once sterilized canning jars are filled with food items and brand new jar lids are placed on each (with reusable rings finger tightened around the top of them) they are placed in the rack and lowered into boiling water. Most items call for 20 minutes of boiling - directions are given with canning jars - and a specialized jar remover tool can be used to take them out one at a time and set aside to cool. As the filled jars cool the lids will vacuum seal to the top of the jars forming a slight indentation on the top and a "pop" sound. The food is now preserved for storage without refrigeration. The appropriate food for this type of canning is jellies, jams, pickles and NOT meat containing items which are "pressure canned".

What are some of the precautions that should be followed when using a canner?

There are a few risks associated with the use of a pressure canner. These include structural failure, escaping steam or boiling water due to seal failure and also the danger of opening the canner too early.


Does your canner need to be full to can?

Your cooking time and temperature will be more accurate if your canner is full of processed jars, not full of water. If you put too much water in your canner it will overflow.


How are peas canned?

What you need: Pressure canner, large pan for boiling water, Clean jars, rims, new lids, Colander (strainer), Butter knife, and a Small pan for heating lids. First, Heat a large pan of water on the stove, bringing it to a boil and then keeping it hot. Sort peas and pitch any that are too old (the pea will be splitting). Then fill your sink with water and wash the peas. Dip the peas out of the water and put them in a colander to drain. In clean jars (this article will deal with pints), pour peas into the jars. Then, take the boiling water from the pan and carefully fill the jars to within 1 inch of the rim. Run a butter knife around the inside of the jar to get out air bubbles that may be trapped in the peas. Wipe the rim of the canning jar with a paper towel. Place a heated lid and ring on the jar and put it in the canner. Fill the canner with the appropriate amount of water according to YOUR pressure canner's instructions. Make sure you use cold water. This is so that the peas will cook while the water is heating in the canner. And run the canner for the amount of time it states.


What should the water level be in the pressure canner for 4 quart jars of venison?

Water level in all pressure canners should be 2-3 inches with the jars in place to operate safely and effectively. Be careful not to overfill the canner, sufficient head-space must be maintained for the canner to work safely.


How does a pressure canner work for canning foods?

A pressure canner allows the temperature of the food to be raised beyond the normal boiling point of water. This kills nearly all microorganisms in the food. When the pressure is released, the lids are immediately added. As the jars cool, a vacuum is created under the lid that seals the jar against decay.


What is the difference between a pressure cooker and canner?

Some things are canned in a hot water bath. They do not need to be in a pressure cooker. A canner is just a tall pot with a lid. The food in the jars is heated close to boiling with the lids loosely on. After it is heated, the jars are removed and the lids tightened. As the food cools, a vacuum will form in the jar sealing it.

How can you can green beans?

Like other veggies, canning beans requires a pressure canner. Other acidic fruits, salsa and jams can be canned with a hot water bath canner. Pressure Canners will have directions in them for canning beans, depending on the type of bean you are canning. (When I was young, my mother used to can green beans in a hot water canner. We would put fresh green beans in jars with water, put the lids on loosely, place in the canner containing the same temperature water and heat to boiling, Boil for several minutes, then remove the jars and tighten the lids. As the jars cooled, the water and hot air inside would shrink, causing a vacuum which made the jar lids pop down and seal tight. We then put the jars in a cool dark storage area and ate them all year until the next harvest. Any jar that failed to seal became that nights supper. Boiling the jars and the water inside them killed any bacteria that could cause the beans to spoil, as well as anything that could cause disease. This method has been in use for hundreds of years and more information is readily available on the net.)
