12 Steps to Canning Corn Step 1, Check Jars Check the jars to make sure that none have nicks on the rims, cracks or sharp edges. We have used mayonnaise jars but they have had too many failures. They have thinner rims and are not as strong to handle the heat. The failure rate did not warrant using them. Often you can buy Ball, Mason, or Kerr canning jars at Goodwill or from ads in the newspaper at good prices. For corn we use narrow-mouth jars. Both Ball and Kerr have sold their home canning divisions to Allrista that sells under license to Kerr and Ball. We still have some old Atlas canning jars and a few that are colored slightly green (real old timers). ⇦ Back to Step 12 On to Step 2 ⇨Back to Steps in Canning Corn Page 1 |
