This sweet and spicy blackberry jalapeño jam is the perfect balance of fruit and heat. Quick and easy to make, it’s great on toast, cheese boards, or as a glaze for meats.

Ingredients

Scale
  • 4 cups fresh blackberries (about 18 ounces)
  • 2 medium jalapeños
  • 3 cups granulated sugar
  • 3 tablespoons fresh lemon juice
  • 1 packet (1.75 ounces) powdered pectin
  • 1 teaspoon vanilla extract (optional)
  • Pinch of smoked paprika (optional)
  • 1 tablespoon finely grated fresh ginger (optional)

Instructions

  1. Wash the blackberries gently and let them drain. Dice the jalapeños into small pieces (about 1/4-inch cubes). Remove seeds and membranes for less heat, or keep them for more.
  2. Add the blackberries to a large heavy-bottomed pot and crush them with a potato masher or the back of a wooden spoon. Leave some berries whole for texture.
  3. Stir in the diced jalapeños and lemon juice. Bring the mixture to a gentle boil over medium-high heat, stirring frequently. Cook for about 5 minutes.
  4. Sprinkle the pectin over the hot fruit mixture and stir vigorously for 1-2 minutes until completely dissolved. Bring to a full rolling boil.
  5. Pour in the sugar all at once and stir continuously. Bring back to a rolling boil and boil hard for exactly 1 minute, stirring constantly.
  6. Remove from heat. Test for doneness using a thermometer (220°F) or the freezer plate method (jam wrinkles when pushed). If still runny, boil another 30-60 seconds and test again.
  7. Let the jam sit for 5 minutes. Skim off any foam. Ladle into sterilized jars, leaving 1/4-inch headspace. Wipe rims, screw on lids, and let cool at room temperature.

Notes

Don’t double the batch for best results. Wear gloves when handling jalapeños. Use a wide pot for faster evaporation. Don’t skip the lemon juice. Let jam cool completely before judging texture.
