Ingredients

  • 2 cups fresh watermelon diced or cubed
  • Granulated sugar amount depends on desired sweetness, typically ½ to 1 cup

Instructions

  • Place the diced or cubed fresh watermelon in a saucepan.
  • Add granulated sugar to the saucepan, starting with ½ cup, and adjust according to your desired level of sweetness.
  • Heat the mixture over medium heat, stirring constantly to dissolve the sugar.
  • Bring the mixture to a simmer and allow to cook for about 10 minutes, or until the watermelon pieces have softened.
  • Use a potato masher or a spatula to press the watermelon and release all the juices.
  • Remove the saucepan from the heat and let the watermelon syrup cool.
  • Once cooled, strain the syrup through a fine-mesh sieve or cheesecloth to remove any remaining watermelon solids, leaving you with a smooth liquid.
  • Transfer the watermelon simple syrup to a clean glass jar or bottle for storage.
  • Seal the jar or bottle tightly and refrigerate the syrup until ready to use.

Notes

  • Storing: Store the syrup in a mason jar or other airtight container in the refrigerator for up to two weeks. It can also be frozen for up to three months.
  • Freeze Individual Portions: If you’re going to freeze it, I’ve found that the best way is by pouring it into an ice tray so that you’ll have individual portions. Once frozen, transfer the cubes to a freezer-safe container, so you can use them as needed. 
  • Use a Ripe Watermelon: Be sure your watermelon is ripe for optimal flavor and sweetness.
  • Adjust the Sugar: When adding the sugar to the saucepan, start with ½ cup and add more depending on your desired level of sweetness.
