Step 1

Step 2

Blend together until it forms a slushie texture. If the texture is too thick you can add a splash of water or juice.

Step 3

Transfer the slushie to your glasses and garnish with some lime, watermelon or a sprig of mint.

Recipe Variations

While the classic watermelon-lime combo is delicious, don’t hesitate to get creative with your slushie. Try incorporating other fruits like strawberries, mangoes, or even cucumber for a unique twist. You can also experiment with different herbs like mint or basil to add depth of flavor.

Expert Tips for Making a Watermelon Slushie

Prep Ahead: Cut your watermelon into chunks and freeze them in a single layer on a baking sheet before transferring to a freezer bag. This ensures quick blending and prevents clumping.
Add Liquid Sparingly: Start with a small amount of lime juice and adjust according to your taste preferences. You can always add more, but you can’t take it away!
Texture Matters: For a slushie with the perfect consistency, blend the frozen watermelon in short pulses until it reaches a slushy texture. Avoid over-blending, or you’ll end up with a watery slushie.
Sweeten Naturally: If your watermelon isn’t as sweet as you’d like, try adding a touch of honey or agave syrup to sweeten the slushie.
Garnish: Garnish your slushie with a wedge of lime, a sprig of mint, or a slice of watermelon on the rim of the glass.
