Watermelon Lemonade Slush

Instructions

1. Line a baking sheet with parchment paper or a silicone mat. Place the watermelon cubes on the prepared sheet and freeze for 4 hours or until frozen solid (see note).
2. Meanwhile, in a small pot, bring the water, lemon juice and sugar to a boil. Simmer until the sugar has dissolved. Refrigerate the syrup until ready to use.
3. In a blender or food processor, purée the watermelon cubes and cooled syrup until thick and slushy.
4. Serve immediately, adding a wide straw to each glass.
