Watermelon Slushie

Are you ready for a refreshing summer treat? This delicious Watermelon Slushie is a fun summertime kitchen project, inspired by one of our favorite island delicacies: Hawaiian shave ice! A bit like a snow cone, shave ice is made by “shaving” blocks of ice into feathery flakes that are flavored with a fresh fruit syrup. Blenders don’t always do a great job of recreating the soft feel of the real thing, which is why we’ve come up with an easy and fun alternative: freezing part of the watermelon before blending. The result is a chunk-free, lightly sweet, flavorful fruit slushie that will transport you to the Pacific. Ready to cool down? Let’s go!
