Boiling is the most common and recommended method for sterilizing canning jars at home. However, other methods exist:
- Dishwasher: Using the sanitize cycle in your dishwasher is an alternative method.
- Pressure Cooker: This method is particularly useful for sterilizing large quantities of jars.
Tips for Effective Jar Sterilization:
- Clean Jars: Wash the jars thoroughly with soap and water before boiling.
- Avoid Overcrowding: Leave space between the jars in the pot to ensure proper heat distribution.
- Keep Water Boiling: Maintain a rolling boil throughout the sterilization process.
