Unlike other simple syrups, this is a no cook homemade watermelon syrup. Otherwise known as a cold pressed syrup. A bit more time is involved here before you get to enjoy your watermelon simple syrup, but it’s worth it though!


  • Watermelon – Ideally fresh watermelon would always be in season, so you might not always get a great one. A seedless watermelon or a seeded one is perfectly fine.
  • White Granulated Sugar
  • Lemon Juice – Fresh is best, fresh lime juice is also acceptable.
  • Dash of Salt

Other sugars used in making homemade simple syrups

Cane Sugar – Cane sugar syrup is earthier, bolder, and gives a toasted sugar flavor than white sugar. Not as strong as turbinado or molasses.

Brown Sugar – This syrup is called Demerara Syrup. Great for coffee cocktails and darker beverages.

Palm Sugar – Golden in color with a cotton candy sweetness.

Honey – 3:2 honey to water ratio.

Agave Nectar– 2:1 agave to water.

Drink Responsibly & Enjoy!


– Cut your watermelons uniformly into 1-inch cubes so they infuse quickly and evenly during the refrigeration process.
– For best results, use ripe but firm fruit when making this recipe – too ripe and it won’t flavor properly; too firm and it won’t mash easily enough. Either seeded or seedless watermelon is fine.
– If you don’t like tartness in your syrup add extra sugar; if you want more tanginess add extra lemon juice.

How long can I store my simple syrup?

You can keep it stored in your fridge for up to three days.

What other fruits can I use in place of watermelon?

Try experimenting with other fruits such as strawberries, raspberries, and blackberries for unique flavor combinations!

Why should I let the syrup chill overnight?

Refrigerating overnight allows for all flavors to infuse evenly for maximum taste potential! This is called cold process syrup. Making homemade watermelon syrup this way will ensure we get maximum fresh watermelon flavor. Cooking the syrup lessens the flavor of fresh watermelon.
