Boiling mason jars before canning is a crucial step that cannot be skipped. Mason jars must be sterilized, and submerging them into hot water for at least 10 minutes is the most effective way to achieve sterilization.
Here are some reasons why you should boil your mason jars before canning:
Sterilization: Boiling mason jars in hot water kills off any bacteria that may be lingering on them. This ensures that the food being canned will remain fresh and safe to eat for a long period of time.
Prevents cracking: Rapid changes in temperature can cause glass jars to crack. By boiling the jars slowly, you reduce the risk of them breaking in the canner or during storage.
Better seal: Boiling the mason jars softens the rubberized sealing compound on the lids, which allows for a tighter seal. This can prevent air from getting into the jar and causing the food to spoil.
Easy to do: Boiling mason jars is a simple process that anyone can do at home. It doesn’t require any special equipment or tools, which makes it an accessible step for beginners.
Overall, boiling mason jars before canning is a crucial step that should not be ignored. It ensures that your canned food is safe, fresh, and will last a long time in storage.
