This simple homemade watermelon syrup recipe is bursting with the flavor of fresh watermelon! It's absolutely perfect for easy entertaining and making refreshing Summer cocktails and sodas.
To make this simple syrup recipe all you need is a fresh, seedless watermelon and some pure cane sugar.
Pro Tip: How To Pick A Perfect Watermelon
The best watermelon syrup comes from the sweetest, ripest watermelons. We recommend making this recipe in the Summer months, during the peak of watermelon season. Here are a few tips for selecting the best whole watermelons at the market:
- Look for round melons. Round, ball-shaped melons are sweeter and juicier. Elongated watermelons tend to be more watery and have less sugar and less flavor.
- Find a melon with a golden yellow or orange field spot. The color of the field spot (the side of the watermelon that grew on the earth) can be a good indicator of how ripe it is. Creamy yellow and orange field spots are a good sign that the watermelon was allowed to fully ripen before being cut from the vine. Watermelons with a white field spot are not ripe.
- Chose a melon with lots of webbing! The webbing pattern on watermelon rinds is a good thing! Those criss-cross lines on the exterior of the fruit are actually scarring from pollination. The more webbing, the sweeter the fruit!
- Avoid shiny rinds and green stems! For the ripest watermelons, look for dried brown stems and darkly colored, dull rinds.
The best part of this recipe is that it is SO QUICK and SO EASY. This recipe is for a cold process watermelon syrup that does not use any heat. This method gives you the freshest watermelon flavor with a vibrant pink coloring. Here's how to make watermelon syrup:
Step By Step
1. First, start by cutting your watermelon in chunks or cubes. Remove any hard black seeds, but don't worry about the white ones - those will get strained out later. Add your watermelon chunks to a blender (or food processor). Puree on high speed until smooth.
2. Next, add your measured sugar to a mason jar (or other tightly-lidded container). Set a funnel and a fine-mesh sieve over the jar. Strain the fresh watermelon into the jar. Discard of any remaining watermelon pulp.
3. Finally, secure the lid on the mason jar. Shake vigorously for 30 - 60 seconds, or until the sugar dissolves completely. Viola! You're very own watermelon syrup is ready to use!
