Sterilize Canning Jars

By Erin Huffstetler, About.com

To prevent food spoilage, canning jars need to be sterilized. Grab your canner and some jars, and let's get started.

Difficulty: Easy
Time Required: 15 minutes
Here's How:
  1. Place your jars in a canner right side up.

  2. Then, fill the canner with water, stopping an inch above the jars.

  3. Bring the water to a boil and continue boiling for 10 minutes.

  4. Reduce the heat; and keep the jars in the hot water until you're ready to fill them.

    -sterilization instructions adhere to current USDA guidelines

Tips:
  1. If you live above 1,000 feet in altitude, add one minute of boiling time for each 1,000 foot increase in elevation.
  2. It is not necessary to sterilize jars for fruits, tomatoes and pickled or fermented foods to be processed in a water-bath canner for 10 minutes or more. It is also not necessary to sterilize jars for vegetables, meats or fruits to be processed in a pressure canner. In both instances, sterilization will occur during processing.
