Crowberry (Empetrum nigrum) is also known in English as blackberry or mossberry. Crowberry bushes are small, evergreen shrubs that grow very close to the ground. Their leaves are small, green and needle-like. The flowers are lavender in color. The round berries are blue/black in color and measure 0.15 to 0.40 inches. Crowberries are found in most parts of �ֻ�ֱ��. Pick crowberries in the fall, gathering larger berries and leaving the smaller ones to ripen. Berries that overwinter can be collected in the spring. Crowberries become sweeter after the first freeze, but they are softer and burst more easily when picked. If you decide to pick before the first freeze, you can freeze the berries and this will increase their sweetness. Cooking also increases the sweetness and flavor, making this berry a wonderful ingredient in juices, jellies and pies.

Nutrition and Health

Crowberries are a favorite treat, especially in the northern parts of �ֻ�ֱ��. Although they have been an important part of �ֻ�ֱ�� Native diets for centuries, crowberries are gaining in popularity as people realize their high nutritional value. Crowberries are often mixed with blueberries for jam, pie and akutuq, which is a traditional ice cream-like dessert.

Crowberries are an excellent source of fiber and antioxidants. Antioxidants are biochemicals important to the healthy functioning of the body. The oxygen radical absorption capacity test (ORAC) is the main way researchers measure antioxidants in foods. Crowberries have a higher ORAC score than most blueberries found in �ֻ�ֱ��. Crowberries have an ORAC score of 94, and a score over 40 is considered very high. A Norwegian study showed that the antioxidants are present, yet reduced, in products such as juice, jelly and wine.

Storage and Preservation

How to Clean and Store

To clean crowberries, spread a clean, dry terry cloth towel over a slanted surface, such as a cutting board with one end propped up a few inches above the other. Gently roll the berries down the towel; most of the debris and leaves will cling to the towel, while the berries roll off. Crowberries should be stored covered in the refrigerator and will keep up to one week.

How to Freeze

Arrange dry, fresh crowberries in one layer on a cookie sheet and place the cookie sheet in the freezer. When frozen, transfer the berries to freezer containers and mark with the date and contents. Properly frozen, crowberries will keep their quality up to two years.

How to Dry

Crowberries have many small seeds and a tough skin, which makes them less suitable for drying.

How to Extract Juice

Combine 8 cups of crowberries and 1 cup water. Crush berries. Bring to a boil and simmer 10 minutes. Strain through a jelly bag or several layers of cheesecloth in a colander. Let the juice drip into a bowl. For clear juice, do not twist or press the jelly bag or cheesecloth. For long-term storage, the juice should be frozen or canned.

Yield: 4 cups

Hot Pack Canning for Juice

Heat juice, stirring occasionally, until it begins to boil. Pour into hot jars, leaving ¼ inch headspace. Wipe jar rims. Adjust lids. Process in a boiling water canner.

• Sterilized pints or quarts: 5 minutes
• Half gallons: 10 minutes

How to Prepare Puree

Cooked method: Add 1 cup of water to 4 cups of crowberries. Cook until skins have popped. Press through a food mill or strainer. Discard skins and seeds.

Yield: 2 cups

Uncooked method: Rinse 4 cups of crowberries, drain, put in a blender and blend until the consistency of a thick puree.

Yield: 2 cups

To freeze: Pack into rigid containers leaving ½ inch headspace for expansion. Seal, mark with the date and contents, and freeze.

To can: Fill hot jars with hot puree, leaving ¼ inch headspace. Process quarts or pints in a boiling water bath for 15 minutes. Purees also can be processed in a dial gauge pressure canner for 8 minutes at 6 pounds pressure or at 5 pounds pressure in a weighted gauge canner. For more information on pressure canning, contact your local Cooperative Extension Service office.

Recipes

Crowberry Syrup

• 1 cup crowberry juice
• 2 cups sugar
• 1 teaspoon lemon juice

Combine ingredients in saucepan; heat to 160 degrees F. Use a candy thermometer; do not boil. The syrup is ready to use over waffles, pancakes, hot biscuits, ice cream and other desserts. Syrup will keep up to six months in the refrigerator without crystalizing.

For long-term storage: Sterilize pint or half-pint canning jars and wash and dry lids; immediately pour hot syrup into hot canning jars, leaving ¼ inch headspace. Wipe jar rims and add two-piece lids. Process 5 minutes in a boiling water bath.

Yield: 2 cups

Crowberry Orange Jelly

• 2 cups crowberry juice
• 1½ cups orange juice
• 1 package powdered pectin (1¾ ounce)
• 4½ cups sugar

Sterilize pint or half-pint canning jars and wash and dry lids. Measure sugar and set aside. Measure prepared crowberry juice and orange juice into a large saucepan. Add the pectin and stir until dissolved. Bring to a rolling boil that cannot be stirred down. Add sugar all at once.

Stir constantly as it again comes to a rolling boil and boil hard for 1 minute. Remove from heat and quickly skim off foam. Immediately pour jelly into hot canning jars, leaving ¼ inch headspace. Wipe jar rims and add two-piece lids. Process 5 minutes in a boiling water bath.

Yield: 5 cups

Crowberry Freezer Jelly

• 3 cups crowberry juice
• 4½ cups sugar
• 1 package powdered pectin (1¾ ounce)
• ½ cup water

Add juice and sugar mixture to the pectin mixture. Stir until all the sugar is dissolved. Pour jelly into freezer containers. Cover with tight lids. Let stand at room temperature until set, which will be from 6 hours to overnight. Label containers with date and contents, and freeze. Refrigerate after opening. If not frozen, keep refrigerated and use within 6 weeks.
