Wash canning jars, lids and bands in hot soapy water.
Place jars in a large pot and fill the pot with enough water to cover the jars. Bring to a simmer (180°F) and simmer for at least 10 minutes—this will prevent the jars from breaking when filled with hot preserves or when transferred to the boiling water bath. Keep the jars in simmering water until ready to fill. You can also wash and dry jars in the dishwasher; keep jars in dishwasher with the door closed (to keep them warm) and remove them as needed.
