| Chicken | Quart | 10 | 75 |
Finishing Up the Canning Process
Once your timer goes off, it’s crucial to follow proper techniques for finishing the process.
Step 1: Releasing the Pressure
Turn off the heat and allow the pressure to release naturally. This can take a while, but it’s essential for safety. Once the pressure has returned to zero, the float valve will drop.
Step 2: Opening the Lid
Remove the lid carefully, tilting it away from you to avoid steam burns. Let the jars stand for a few minutes inside the cooker.
Step 3: Removing the Jars
Using the jar lifter, gently extract the jars from the cooker and place them on a clean kitchen towel or cooling rack.
Step 4: Cooling and Sealing the Jars
Leave the jars to cool undisturbed for 12 to 24 hours. Check the seals by pressing down in the center of each lid—if it doesn’t pop back, it’s sealed correctly.
Storage and Enjoying Your Canned Goods
Once your jars are cool and sealed, store them in a cool, dark place.
