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!
Mix all ingredients in large pot. Bring to a boil.
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.
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.
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.
