1. Use tested recipes and follow instructions carefully. Check with your local Cooperative
Agricultural Extension Service or a manufacturer of glass jars for the latest canning
information.
2. Use flat-bottomed canners only. Heat is spread more evenly when the bottom surface is
flat.
3. Center canner on the burner grate.
4. Start with hot water and a high heat setting to reduce the time it takes to bring the water
to a boil; then reduce the heat setting as low as possible to maintain a constant boil.
5. It is best to can small amounts and light loads.
Prevent damage to cooktop and burner grates:
1. Do not use water bath or pressure canners that extend more than one inch beyond the
edge of the burner grate.
2. Do not leave water bath or pressure canners on high heat for an extended amount of time.
3. Alternate surface units between each batch to allow the units and surrounding surfaces to
cool down. Try to avoid canning on the same burner unit all day.
Safe canning requires that harmful micro-organisms are destroyed and the jars
are sealed completely. When canning in a water bath canner, a gentle but steady boil must be
maintained continuously for the required time.
