Choose ripe, mature fruit of ideal quality for eating fresh or cooking. Wash and peel pears. Cut lengthwise in halves and remove core. A melon baller or metal measuring spoon is suitable for coring pears.
Raw packs make poor quality pears.
Boil drained pears 5 minutes in syrup, juice, or water. Adjust lids and process. This amount is also adequate for a 4 quart load. Heat water and sugar together. Bring to a boil and pour over raw fruits in jars.
