Oregon Grape Jam

Oregon grapesJelly isn’t much in style these days, I’ve noticed. Many people consider it too sweet, otherwise bland, and nearly devoid of nutritional value. I feel that way about many kinds of jelly myself. Who would choose strawberry jelly over strawberry jam, raspberry jelly over raspberry jam? Why throw out all of the fruit’s fiber and sacrifice the appealing texture that fiber provides?

Some fruits, though, are too fibrous or seedy for a mashed jam. When they also have high levels of pectin and acid, they are perfect for jelly. Oregon grape, Mahonia aquifolium, is one of these fruits.* I love the dark, tart, spicy jelly I make from the Oregon grapes growing beneath the bigleaf maple near our chicken house.

Still, some people would always choose a jar labeled jam over one labeled jelly. So, last summer, for the first time, I decided to try making Oregon grape jam. Because Oregon grapes are seedy—a quarter of the weight of each berry is in its three seeds—I decided I would strain out the seeds, but I would still include some of the fiber that distinguishes a jam from a jelly. Because Oregon grapes are so rich in pectin, I would add a little liquor to soften the jam. Here is my recipe.

Seedless Oregon Grape Jam

 3 pounds (about 9 cups) stemmed Oregon grapes
About 1 quart water
5 to 6 cups sugar
2 tablespoons brandy or orange liqueur

In a large saucepan, combine the Oregon grapes and enough water to cover them. Cover the pan, and boil the berries gently, stirring occasionally, for 10 minutes. Crush the berries with a potato masher or other tool, and then boil them gently, uncovered, for 10 minutes more.      

Oregon grape seedsPress the berries and their liquid through the fine screen of a food mill or through a strainer, leaving the seeds behind. Measure the purée; you should have 5 to 6 cups. Put the purée into a preserving pan along with the same volume of sugar. Heat the mixture, stirring, over medium heat until the sugar is dissolved, and then raise the heat to medium-high. Boil the mixture until it “sheets” from a spoon or until the temperature reaches 218 degrees F. Immediately remove the pan from the heat, and stir in the brandy or liqueur.

Ladle the jam into sterilized pint or half-pint mason jars. Add lids and rings, and process the jars for 5 minutes in a boiling-water bath.

Makes about 4 pints

Making Oregon grape jam is slightly more work than making Oregon grape jelly, since the latter requires only dripping, not pressing. The result really isn’t much different; both the jelly and the jam turn out opaque, smooth, and richly flavored.

You could vary this recipe by adding spices—a stick of cinnamon, for example—or using another sort of liquor (I used my sister’s homemade liqueur of rosemary and Meyer lemon). If it’s a truly rough texture you want, you could include some or all of the seeds.

 

*Mahonia nervosa, also known as Oregon grape, is a related, shorter species with similar berries that can be used in the same ways as those of Mahonia aquifolia—in jellies, jams, pies, and wine.

The Oregon Grape

Wild Fruit for a Tart and Tasty Jelly

In the woods one day, my friend Jocelyn saw me eat an Oregon grape, tried one herself, and screamed. I was unfazed; just after my daughter, not yet two years old, had eaten her first Oregon grape, she had pantomimed death throes.

If you were to taste one of these little not-grapes—and I urge you to try one—you too might guess that they were poisonous, for they are very tart and a little bitter. But they are rich in pectin and make a fine jelly. Nearly black in color, the jelly has a grape-like but spicier flavor.

In either its tall or short form (Mahonia aquifolium or M. nervosa), Oregon grape is an evergreen shrub with prickly, holly-like leaves and bright yellow blossoms. Though native only to the Pacific Northwest, from northern California to southern British Columbia, the plant is widely grown elsewhere for its beauty and its drought-resistance. I saw it growing in public beds all over Paris, often along with another Northwest native, red-flowering currant.

In summer, Mahonia’s yellow flowers turn to blue berries that hang on the plant for several weeks. The berries are ready to pick when they’re uniformly dark. For three half-pint jars of jelly, you’ll want to collect about three and a half pounds of berries. Just slide your fingers down each bunch, and the berries will fall into your basket.

It’s easy to extract the juice of Oregon grapes with a steam juicer. If you don’t have a steam juicer, simmer the berries, covered, with half their volume of water for fifteen minutes, mashing them after the first ten minutes. Drain the juice through a jelly bag—let the juice drip for several hours—and then boil it for ten minutes to reduce it a bit. From this point on, making jelly is quick and easy.

Oregon Grape Jelly

3 cups Oregon grape juice
2 ¼ cups sugar

Combine the juice and sugar in a wide, heavy-bottomed, nonreactive pan (that is, a pan with a stainless-steel or well-enameled interior surface). Place the pan over medium heat. Stir until the sugar is dissolved, and then raise the heat to medium high. Boil the syrup, skimming occasionally, until it begins to jell. This will take only a few minutes. You can test for jelling by scooping a little of the syrup with a metal spoon and then tipping the spoon high over the pan. You’ll see the drops thicken and slow, and then two drops will run together. That’s the point at which you remove the pan from the heat.

Skim any remaining foam from the surface of the syrup. Immediately pour the syrup into three sterilized half-pint mason jars. Add the jar lids and rings, and process the jars in a boiling-water bath for five minutes.

Remove the jars from the water bath, and let them cool on a rack or pad. Leave them alone until the next day, when the jelly should be firm.
