Wash fruit well. Skin removal is optional: dip fruit in boiling water 30 to 60 seconds until skins loosen, cool quickly, and slip off skins. Halve, pit, and slice if desired; hold peeled fruit in ascorbic acid solution.
For hot pack, bring drained fruit to a boil in syrup, water, apple juice, or white grape juice. Fill jars with hot fruit and cooking liquid, leaving 1/2-inch headspace.
For raw pack, fill jars with raw fruit cut side down and add hot water, juice, or syrup, leaving 1/2-inch headspace. Raw packs make poor-quality apricots.
