The water bath method of sealing glass jars requires that the food itself is acidic or has acidic substances added, and the food can be prepared while sterilizing the glass jars. Remove the sterilized glass jars from the pot with food tongs, turn the heat back on, bring the water to a slight boil, and fill the jars with food.

Place the glass jars on a water bath rack, place the rack in boiling water, remove the glass jars, and once the jars have cooled completely, place them in a dry, cool place. The water bath rack can be put into the water bath or ordinary large pot, and the rack separates the bottom of the glass jar from the bottom of the pot,
