THE FOLLOWING FINAL STEP IS CRUCIAL TO ENSURE A GOOD SEAL:
Once the process is completed and the jars are removed from your canner, Let the bubbling die down (approximately 3-5 minutes), as this is pressure still releasing from the jars. Place a towel over the still hot jars (for safety) and finish tightening the metal bands. Now, let your jars cool naturally and when cool to room temperature, remove the metal band and lift the jar slightly by the lid. It should be well sealed. Your food is ready for storing (store without metal screw bands).
