Pressure Canner

Pressure Canner Method

Follow manufactures instructions for opening and closing the pressure canner. Have 2 to 3 inches of hot water in pressure canner and stand the jars on the rack insert so they are not touching each other or the sides of the pot. Fasten lid and turn on heat. Steam, mixed with air, will start to flow from the vent and then This is about 8 to 10 minutes after the first sign of steam. As the air is driven out from the canner the steam will change from a white vapor or cloud to nearly invisible.

Start processing time when pressure has been reached or when weighted gauge begins to rock. It is then time to close the the pet-cock or regulator. Maintain a steady pressure during processing.

When processing time is up, remove the canner from heat and let the pressure return to zero without assistance. Standard heavy-walled canners take about 30 minutes when loaded with pints and about 45 minutes when loaded with quarts. Do not attempt to cool pot with cold water. This can cause liquid to escape from jars and keep lids from properly sealing. It can also cause pot warpage.

After pressure reaches zero, wait 2 minutes longer and then slowly open or remove the pet-cock or regulator. Unfasten cover and tilt the far side up so any steam remaining will escape away from you. Using a jar lifter, remove each jar and place on a dry, non-metallic surface or towel. Leave space between jars for air circulation.

After jars have cooled, test for seal and the screw bands may be removed if desired. Be sure to label canned jars with content and processing date. Store jars in a cool dark, dry place.
