This easy homemade no pectin black raspberry jam is made with just three ingredients and no special equipment. It’s a simple, forgiving recipe that produces intensely flavored, ruby-dark jam that tastes like pure summer.

Ingredients

Scale
  • 4 cups fresh or frozen black raspberries (about 20 oz)
  • 2 cups granulated sugar (400 g)
  • 2 tablespoons fresh lemon juice (about 1 lemon)
  • Optional: 1/2 teaspoon unsalted butter

Instructions

  1. Prepare your jars and plate: Wash jars and lids in hot soapy water, then place them in a 225°F oven for 15 minutes to sterilize. Pop a small plate in the freezer for the set test.
  2. Combine berries and sugar: In a large pot, add black raspberries and sugar. Stir gently to coat. Let sit for about 10 minutes to draw out juices.
  3. Start cooking: Place pot over medium heat and stir occasionally. After about 5 minutes, add lemon juice and butter (if using).
  4. Bring to a rolling boil: Turn heat to medium-high and bring to a full rolling boil. Boil for 8-12 minutes, stirring frequently, until mixture darkens and thickens.
  5. Test for set: Turn off heat. Spoon a small amount of jam onto the frozen plate. Let sit for 30 seconds, then push with finger. If it wrinkles and holds shape, it’s done. If runny, boil 2-3 more minutes and test again.
  6. Skim foam (optional): Skim off any foam with a spoon.
  7. Fill the jars: Ladle hot jam into sterilized jars, leaving 1/4 inch headspace. Wipe rims clean and screw on lids.
  8. Process or cool: For shelf-stable jam, process jars in a boiling water bath for 10 minutes. If eating within a few weeks, let cool on counter.

Notes

Don’t overcook the jam – it will continue to thicken as it cools. The freezer test is more reliable than a candy thermometer. Let jam rest in pot for 5 minutes before jarring to allow fruit to settle and foam to rise. For best flavor, let jam sit for a few days before eating.
