How To Reprocess Unsealed Canning Jars

By , About.com Guide

When canning your own food you'll occasionally get a jar or a batch of jars that fail to seal after processing. While frustrating, it's a problem that can be resolved easily by reprocessing the jars.
Difficulty: Easy
Time Required: Varies by Canning Recipe
Here's How:
  1. Check the jar (or jars) for nicks along the rim.

  2. If you find a nick, transfer the contents to a new jar. If you don't find any nicks, put a fresh lid on the jar; and secure it with a ring.

  3. Then, reprocess the jar (or jars) using the same processing time as before.

  4. Allow the jars to cool; then check for a good seal.

Tips:
  1. Canning lids can only be used one time, so always start with a new lid
  2. Unsealed jars may be stored in the refrigerator for immediate use
What You Need:
  • A new canning lid
  • A canning ring
  • A canner
