Step 1

Lay the chopped watermelon onto a baking sheet or dish, place in the freezer for 2 hours.

Step 2

Once the watermelon is completely frozen, place it into a high-powered blender with the mint (if using) and blend on high until it turns into a slushie. If you’re having trouble because it’s too frozen, you can let it thaw for a minute or two, or you can add 2 tablespoons of water to get it going.

Step 3

Enjoy immediately.
