3Canning Methods:
There are two safe ways of canning, depending on the type of food being canned. These are the pressure canning method and the boiling water bath method.
Pressure Canning Method: Pressure canning is the only safe method of canning
Note: Although considered fruit, tomatoes a ph value close to 4.6. Therefore you should typically process them in a pressure canner.
Jars of food are placed in 2 to 3 inches of water in a pressure cooker and heated to a temperature of at least 240 °F or above for the correct length of time. Note: This temperature can only be reached in a pressure cooker/canner. Never attempt to can
STEPS FOR PRESSURE CANNER METHOD
Processing Instructions: Fill the jars. Allow the proper headspace according to processing directions for specific foods. This is necessary so that all the extra air will be removed during processing, and a tight vacuum seal will be formed.
To make sure that air bubbles have not
been trapped inside the jar, run a bubble freer or any plastic or
Wipe off the rims of the jars with a clean, damp cloth.
Screw on the lids, but not too tightly — air needs to escape during processing.
Set the jars of food on the rack in the canner so steam can flow around each jar. Add
When the processing is completed, carefully remove the canner from the heat. If the canner is too heavy, simply turn it off. Let the pressure in the canner drop to zero using the natural release method. Do not use the cold water pressure release method for pressure canning. Never use the automatic release method to hasten the reduction in pressure when canning foods.
When the canner is depressurized, unfasten the lid and tilt the far side up, so the steam escapes away from you.
Use a jar lifter to carefully remove the jars from the canner.Place the hot jars on a rack, dry towels, boards or newspaper , right side up to prevent the jars from breaking on contact with a cold surface .. Leave at least 1inch of space between the jars.
Do not tighten the lids. Allow the jars to cool, untouched for 12 to 24 hours. Boiling Water Bath Method:
