If you have a lot of watermelon, or just love watermelon, watermelon syrup is a fabulous treat to make with the fresh fruit.  It's amazing in homemade Italian sodas, or drizzled over vanilla ice cream, or on pancakes...  you get the idea.  It's all the flavor of fresh watermelon in a bottle.

  • one cup sugar

How to Make Watermelon Syrup

But how do you get the watermelon juice?  Start with whole watermelons (preferably a seedless watermelon).  Just cut into watermelon chunks, throw it in a blender or food processor, and strain the watermelon puree through a fine-mesh sieve.

A Note on Sweeteners in Watermelon Syrup:

If you don't want to use a cup of sugar in your watermelon syrup, you can use a neutral substitute, like agave nectar.  I would not recommend using honey, maple syrup, or brown sugar in this recipe, because those sweeteners would overshadow the wonderful watermelon flavor we're trying to capture.

You can omit the sugar entirely, if you'd prefer.  It obviously won't be as sweet, or as thick, but reduced watermelon juice on its own is absolutely delicious, too.  Sugar acts as a preservative, so watermelon syrup made without sugar won't last as long, even in the fridge.

Combine the sugar and watermelon juice, and bring to a boil over medium-high heat.  Depending on the strainer you used earlier, you may notice solid material floating to the top of the mixture.  Use a fine mesh strainer to scoop it out.  Boil until the liquid is reduced by half.
