Canning Pear Jam
16 Steps -- Step 10

Heat the Jars

Paul puts the jars we will use inverted in a shallow pan with an inch of water. He will turn on the heat in a moderate temperature so the water will gently boil. This sterilizes and heats the jars. You should not put hot jam in a cold jar. We will put our jam in half pints. You may have to tip the jars from time to time in case the water is all drawn up into the jars.
