Sweet-Tart Watermelon Lemonade and Icy Watermelon Cubes


Watermelon is so refreshing in summer, and it always goes on sale for a steal. But it can be hard for our small household to finish an entire watermelon. To make sure we don’t waste an ounce of that sweet, juicy flesh, I use a few naturally dairy-free recipes and ideas. If we have strawberries on hand, I blend delicious Strawberry Watermelon Smoothies. If we have lemons on hand, then I make the sweet-tart watermelon lemonade recipe below.

Any leftover watermelon gets pureed and frozen into icy watermelon cubes! They’re perfect for blending into smoothies, floating in drinks, or making into single servings of this sweet-tart watermelon lemonade.
