An automatic pressure canning appliance for high-acid recipes has pre-programmed canning recipe programs (i.e., pre-determined times and temperatures) with which it has been programmed to can the high-acid food that the user wishes to can. A user selects the canning recipe program for the food to be canned via a canning recipe program input on a control panel of the appliance. The appliance processes the food to be canned (which is in jars in the appliance) in a pure steam environment for a pre-programmed processing time of the selected canning recipe program.
