Print Recipe

This easy homemade blackberry jam uses just three ingredients and no pectin. It’s sweet, slightly tart, and perfect for beginners, with a soft, spreadable texture and pure fruit flavor.

Ingredients

Scale
  • 3 pounds fresh or frozen blackberries
  • 3 cups granulated sugar
  • 2 tablespoons fresh lemon juice

Instructions

  1. Prepare your blackberries. If using fresh, rinse gently and pick out stems or leaves. If using frozen, thaw completely in a colander set over a bowl, reserving the juice.
  2. Mash the berries in a large pot using a potato masher or the back of a wooden spoon, leaving some chunks for texture.
  3. Add the sugar and lemon juice to the mashed berries. Stir to combine and let sit for 10 minutes to draw out juice and dissolve sugar.
  4. Place the pot over medium heat and stir constantly until the sugar dissolves completely, about 5-7 minutes.
  5. Increase heat to medium-high and bring to a rolling boil. Boil for 15 minutes, stirring occasionally, skimming off any foam that forms.
  6. Check for doneness using the wrinkle test: drop a small spoonful of jam onto a cold plate, let it sit for 30 seconds, then push it with your finger. If it wrinkles and doesn’t run back together, it’s done. If still runny, boil for another 2-3 minutes and test again.
  7. Remove from heat and let the jam rest for 5 minutes. Give it a gentle stir to redistribute fruit.
  8. Fill sterilized jars using a funnel and ladle, leaving 1/4 inch headspace. Wipe rims, place lids, and screw bands fingertip-tight.
  9. Optional: Process jars in a boiling water bath for 10 minutes for shelf stability. Otherwise, store in the refrigerator.

Notes

Don’t walk away during the boil to prevent boil-over. Use the wrinkle test instead of a candy thermometer for reliable doneness. Let jam rest 5 minutes before jarring to prevent fruit from floating. Work clean with a bowl of warm soapy water nearby.
