Ingredients

  • 3 pounds fresh or frozen blackberries

  • 2 cups granulated sugar

  • ¼ cup fresh lime juice

  • 1 ½ tablespoons grated fresh ginger

  • ¼ teaspoon salt

Directions

  1. Combine blackberries and sugar in a large saucepan. Let stand for 1 hour, stirring occasionally.

  2. Place the blackberry mixture over medium-high heat; bring to a boil, stirring often and mashing the berries with the back of a spoon to help break them down, until the mixture is thick and jammy, 15 to 20 minutes. Set a fine-mesh strainer over a large heatproof bowl. Strain half of the blackberry mixture, pressing with the back of the spoon to extract remaining juices. Return the strained blackberry juice to the saucepan; discard the solids in the strainer.

  3. Reduce heat to medium-low; place a candy thermometer in the pan. Stir in lime juice, ginger and salt. Continue to cook, stirring constantly, until the mixture reaches 220°F, 15 to 20 minutes more. (The jam is ready when the bubbles become more stable and the mixture is thickened enough that you can see the bottom of the saucepan when you stir.) Remove from heat and let stand for 10 minutes.

  4. Ladle the jam evenly among 4 (1-pint) clean canning jars and place lids on the jars. Let stand at room temperature until completely cooled, about 3 hours.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
