Quantity: 1 crate (24 qt) yields 32 to 36 frozen pints. 1-1/3 to 1-1/2 pints yields 1 frozen pint.
Quality: Select full-flavored, ripe berries.
1. Wash berries and remove leaves, stems and immature or defective berries.
2. Follow directions below for style of pack desired.
Unsweetened 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.
Puree: 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.
