Did you know you can make fruit-flavored simple syrups without heat or water? Sugar is hygroscopic, meaning it pulls the moisture from whatever it’s added to. Cooking fruit to make simple syrups can alter the taste, but this process doesn’t disturb the fresh fruit water.

To sum it up, coating watermelon in sugar pulls the juice from the fruit, creating a sweet, sticky syrup with pure watermelon flavor.

So, you should make this watermelon syrup because…

  • Using a no-cook, cold process method doesn’t alter the flavor of the fruit.
  • If stored properly, it lasts for 2 weeks in the fridge or 6 months in the freezer.
  • The best way to add natural watermelon flavor to drinks and desserts.

Ready to make watermelon-infused simple syrup? Plan ahead, so you have plenty of time to soak the watermelon in the sugar, and let’s do it.


🍉 Ingredients

Using a cold process to make simple syrup eliminates the need for water, so all you will need is:

  • Watermelon – The star of this simple syrup flavor. Seedless varieties are easier to strain, but you can use any perfectly ripened watermelon. You’ll need about 2 heaping cups.
  • Sugar – To sweeten the syrup, you’ll need sugar. You can use any sugar here, but granulated sugar and caster sugar work best.
