Preparation Select full-flavored, ripe berries. Remove leaves, stems and immature or defective berries.
Dry Pack Do not wash blueberries. Washing results in a tougher skinned product. Pack berries into containers, leaving headspace. Berries can also be frozen first on a tray and then packed into containers as soon as they are frozen. Seal and freeze. Wash before using.
Crushed or Puréed Wash the blueberries. Crush, press berries through a fine sieve, or purée in a blender or food processor. Mix 1 to 1 1/8 cups of sugar with each quart (2 pounds) of crushed berries or purée. Stir until sugar is dissolved. Pack into containers, leaving headspace. Seal and freeze.
