Watermelon Jam

HOMEMADE Watermelon Jam! This easy to make jam recipe uses fresh watermelon juice to make a healthy jam.  No pectin is needed for this recipe, just throw it in the refrigerator when it's done! This is one of the best fruit jams, I love eating it on toast!


  • 16 cups watermelon juice seeds out
  • 1 cup sugar
  • 1 tablespoon lemon juice
  • 2 tablespoons cinnamon


  1. Mix all ingredients in large pot. Bring to a boil.
  2. Reduce heat to medium high. Keep a eye on this so it doesn't boil over. Skim foam as it rises. Check and stir every 15 minutes.
  3. Continue to boil for 2-3 hours (mine took 3 hours). Depending if you reduce the recipe yours might done faster, so keep checking to make sure it doesn't burn.
  4. Let sit for 5 minutes. Immediately place in mason jar. The jam hardens quickly so if you let it sit for longer it will be tough getting it out of the pot.
  5. Place in refrigerator and enjoy!
