Question: How do you make sure the lid on a newly canned jar of homemade jam is sealed properly?
Option 0: Fill a large pot with tap water (enough to the water will be 2 inches above the top of the canning jar) and bring it to a boil. Place the sealed jar of jam into the pot and allow it to sit for 10 minutes. After 10 minutes has elapsed, grasp the jar with your hands and pull it out of the water. Allow it to cool overnight. The next day, press on the center of the jar's lid. If it makes a popping noise the jar is not sealed properly. You will need to repeat the sealing process until the center of the jar's lid does not pop up.
