Canning Cherries Quantity: An average of 17-1/2 pounds is needed per canner load of 7 quarts; an average of 11 pounds is needed per canner load of 9 pints. A lug weighs 25 pounds and yields 8 to 12 quarts--an average of 2-1/2 pounds per quart. Quality: Select bright, uniformly colored cherries that are mature (of ideal quality for eating fresh or cooking). Procedure: Stem and wash cherries. Remove pits if desired. If pitted, place cherries in water containing ascorbic acid to prevent stem-end discoloration. If canned unpitted, prick skins onopposite sides with a clean needle to prevent splitting. Cherries may be canned in water, apple juice, white-grape juice, or syrup. If syrup is desired, select and prepare preferred type as directed. Hot pack--In a large saucepan add 1/2 cup water, juice, or syrup for each quart of drained fruit and bring to boil. Fill jars with cherries and cooking liquid, leaving 1/2-inch headspace. Raw pack--Add 1/2 cup hot water, juice, or syrup to each jar. Fill jars with drained cherries, shaking down gently as you fill. Add more hot liquid, leaving 1/2-inch headspace. Adjust lids and process. Processing directions for canning cherries in a boiling-water, a dial, or a weighted-gauge canner are given in Table 1, Table 2, and Table 3. Table 1.
