Place the lid on the canner and lock it. Leave the vent open, adjust the heat to medium-high, and bring the canner to a boil.
Once boiling, let the pressure canner to vent steam for 10 minutes, then place the pressure regulator on top of the air vent, and let the pressure rise.
When the canner has reached the correct pressure (10 pounds for weighted gauge or 11 pounds for dial gauge pressure canner), set a timer and process pint jars for 75 minutes, and quarts for 90 minutes at altitudes of less than 1,000 ft.
Adjust the pressure for your altitude if necessary (see chart below), and regulate the heat as needed to maintain a steady pressure.
When the processing time is complete, turn off the heat, and allow the canner to sit until pressure drops to 0. Once the canner is depressurized, let the canner cool additional 10 minutes before removing the lid.
Spread a dry towel on the counter, unlock the cover, and remove it by tilting the lid away from you so that steam does not burn your face.
Allow another 10 minutes for the jars to adjust to the change in pressure. If the jars are still boiling vigorously, let them sit in the canner for another 5 minutes or until the boiling slows.
Use the jar lifter to remove he jars from the canner and place them on the towel. Keep them upright, and don't tighten bands or check the seals yet. Let the jars sit undisturbed for 12 to 24 hours to cool and seal.
After 12 to 24 hours, check to be sure the jar lids have sealed by pushing on the center. The cover should not pop up. The jar failed to seal if the top flexes up and down. Refrigerate it and use it within a few days.
Remove the screw-on bands and wash the jars in warm soapy water to remove any residue. Then label, date, and store the jars in a cool, dark place. Use within 18 months for the best quality. Yields 8 pints or 4 quarts.
