do jars need to be covered with water when pressure canning?
During pressure canning, jars do not need to be covered with water. Instead, a specific amount of liquid (usually water) is added to the jar before processing. This liquid helps to create the necessary steam pressure inside the jar and ensures that the food is heated evenly. Once the processing time is complete, the jars are removed from the canner and allowed to cool at room temperature. The liquid inside the jar will eventually evaporate, leaving behind a vacuum-sealed container of food.
do jars seal as they cool?
Jars seal as they cool due to the formation of a vacuum seal. When hot food is placed in a jar, the air inside the jar expands. As the food cools, the air inside the jar contracts, creating a vacuum. This vacuum seal prevents air and bacteria from entering the jar, which helps to preserve the food. The strength of the vacuum seal depends on the temperature of the food and the amount of headspace in the jar. The higher the temperature of the food, the stronger the vacuum seal will be. The less headspace in the jar, the stronger the vacuum seal will be. Jars can also seal as they cool if they are processed in a boiling water bath or a pressure canner. This process creates a sterile environment inside the jar, which prevents bacteria from growing.
