Quantity: An average of 19 pounds is needed per canner load of 7 quarts; an average of 12-1/4 pounds is needed per canner load of 9 pints. A bushel weighs 48 pounds and yields 16 to 19 quarts-an average of 2-3/4 pounds per quart.
Quality: Select apples that are juicy, crispy, and preferably both sweet and tart.
Procedure: Wash, peel, and core apples. To prevent discoloration, slice apples into water containing ascorbic acid. Raw packs make poor quality products. Place drained slices in large saucepan and add 1 pint water or very light, light, or medium syrup (see
"Preparing and Using Syrups") per 5 pounds of sliced apples. Boil 5 minutes, stirring occasionally to prevent burning. Fill jars with hot slices and hot syrup or water, leaving 1/2-inch headspace. Adjust lids and process.
Processing directions for canning sliced apples in a boiling-water, a dial, or a weighted-gauge canner are given in
