What can I make with watermelons?

This year we grew a bunch of watermelons in the garden.  If you’re looking for a good container fruit to grow, watermelon is the direction you should go in.  On each plant we usually get 3-4 watermelons which quickly adds up when you have a few plants! 

 By the way did you know that watermelon is a fruit and a vegetable? It is a fruit because it grows from a seed. It’s a vegetable because it is harvested and cleared from the field like other vegetables and because it is a member of the same family as pumpkins. I had no idea!

Watermelon Jam Recipe

First, you’ll need watermelon juice which is easy to make.  Remove the seeds from your watermelon and then throw watermelon chunks in a blender or food processor.  Blend until it turns into watermelon juice!

I love making homemade jam with blueberries so I decided this time to make a watermelon jam recipe. And because I think all jam tastes and smells better with a bit of cinnamon we’ll throw some of that in to make it extra special.  This recipe calls for 16 cups of watermelon juice (watermelon is 92% juice) but if you don’t have that much just scale down the recipe.

 Start with a big pot of your watermelon juice.

Bring it to a boil on the stove. Reduce heat to medium high.

And then continue to lightly boil for the next 2-3 hours.  You will see the watermelon start to break down and thicken to a dark jam color.  This is mine after 3 hours.

I’ll let the jam sit for a few minutes to thicken up completely and then I’ll quickly get it in mason jars,  You can see how thick the jam got here.

Ingredients

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

Instructions

  • 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.
  • Place in refrigerator and enjoy!

    Can honey be substituted? I have alpha gal syndrome (from a tick bite) and sugar reacts in my body like food poisoning.

      Hey Candy, I’ve had previous readers that have canned this with a water bath, but I’ve never personally tried. Enjoy the jam!

    I have never heard of watermelon jam and would love to try it. I’ll have to pin and wait because watermelon season is already over here. But I’m just about to make some pear jam and your cinnamon idea sounds perfect. I’ll add a bit to the pears.
