Plum Freezer Jam with Cardamon and Ginger
1/3 cups coarsely chopped Meynard Plums (from about 1 1/4 pounds)
1 (1-inch) piece ginger (about 1 1/2 ounces)
1 1/3 cups sugar
1/4 cup Ball® RealFruit® Instant Pectin
2 tablespoons fresh lemon juice
1/4 teaspoon freshly ground black pepper
1/4 teaspoon ground cardamom
- Bring plums and 1 cup water to a boil in a medium saucepan, then reduce heat to low and simmer until plums begin to soften and liquid is reduced by about half, about 5 minutes.
- Meanwhile, finely grate ginger, then squeeze juice into a small bowl; discard pulp.
- Combine sugar and pectin in a large bowl. Add plum mixture, lemon juice, pepper, cardamom, and 1 tsp. ginger juice (discard any remaining juice), then stir constantly for about 3 minutes to activate pectin. Using a potato masher or fork, break up any large plum pieces, then let cool at least 30 minutes.
- Ladle jam into sterilized jars, leaving 1/2 from the top to allow for expansion. Cover and chill.
