16 Steps to Canning Plums

Step 12, Fill the Steam Canner

Place jars into the steam canner. We put in the steam canner about 2 inches of water up near to the top of the wire rack. A few tablespoons of white vinegar will help to prevent discoloration of the canner. We have heated up the water in the canner getting ready for the jars. The canner will process 9 pints at a time. You certainly can use a water bath for this step if you wish. But don't put cool jars into boiling hot water. The jars may break.
