Growing

Raspberry plants should be planted in early spring. Summer- and fall-bearing varieties are available. Plant raspberries at least 2 feet apart in rows that are spaced 6 to 8 feet apart. As time passes, prune to allow six to eight canes per hill for optimal yield.

See the NDSU Extension Service publications “Starting a Community Orchard in North Dakota” (H1558) and “Refreshing Raspberries” (H38) for more information.

Storage

Use ripe raspberries right away, and throw away any moldy or damaged berries. Store raspberries in the crisper in your refrigerator at 40 F. Try to use the berries within two days after purchase or picking to ensure freshness. Rinse them right before use.

Preservation

Raspberries may be frozen, canned or dried.

Freezing: Raspberries can be frozen in various ways.

Unsweetened pack: Place berries on a tray and place in the freezer. As soon as they are frozen, pack into containers in recipe-size amounts, leaving ½ inch head space. Seal, label with the contents and date, and freeze. Raspberries also may be placed directly into freezer containers or bags and frozen.

Sugar pack: To 1 quart (1a pounds) berries, add ¾ cup sugar and mix carefully. Put into containers, leaving ½ inch head space. Seal, label and freeze.

See the NDSU Extension Service publication “Freezing Fruits” (FN182) for more information.

Canning: Choose ripe but firm, sweet berries with uniform color. Wash 1 or 2 quarts of berries at a time; drain and stem. Prepare syrup if desired (see reference below). Bring syrup to a boil and reduce heat. Spoon prepared berries into hot, clean jars, leaving ½ inch head space. Lightly shake the jars to pack the berries closely (do not crush). Return syrup to boiling. Add the boiling syrup to cover the berries, leaving ½ inch head space. Wipe jar rims and add lids. Process hot-packed berries in pints or quarts in a boiling water-bath canner: 15 minutes (0 to 2,000 feet altitude) or 20 minutes (more than 2,000 feet altitude).

See the NDSU Extension publication “Home Canning Fruit and Fruit Products (FN174) for more information.

Drying: Learn how to make raspberry fruit leather in the NDSU Extension Service publication “Making Fruit Leathers” (FN1586).

Recipes

Raspberry Salad Dressing

In a blender, combine the yogurt, raspberries, vinegar and sugar. Blend until smooth and refrigerate until chilled.

Makes eight servings. Each serving has 35 calories, 0 g fat, 2 g protein, 7 g carbohydrate, 2 g fiber and 25 mg sodium.

Raspberry Jam

Half-fill water-bath canner with hot water; place it on the stove and let the water come to a boil while preparing jam. Crush the raspberries with a potato masher. Mix the raspberries and pectin and heat to boiling, stirring constantly. Add the sugar all at once and stir until dissolved. Continue stirring gently until the mixture comes to a full rolling boil that cannot be stirred down. Start timing for one minute and stir constantly while it continues to boil. Remove from heat. Skim any foam from the jam, and carefully ladle the jam into clean jars using a canning funnel. Fill jars to within ¼ inch of the rim. Wipe the rim with a clean, damp cloth. Quickly apply the lid and fasten with a ring. Process for 10 minutes (when water begins to boil again, start timing) in a boiling-water bath.

Makes eight servings. Each 1-tablespoon serving has 45 calories, 0 g fat, 0 g protein, 12 g carbohydrate, 0 g fiber and 0 mg sodium.
