                You would be hard-pressed to find something more refreshing than watermelon. This cooler is easy to make, beautiful to behold, and not too sweet. You’ll want a pitcher of it in the refrigerator all summer.

Cut watermelon flesh into 2-inch chunks and discard rind. Purée one fourth of watermelon in a blender with 1 Tbsp sugar, 1 tsp lemon juice, 4 cups ice, and a pinch of salt. Strain through a fine-mesh sieve into a large bowl, discarding solids. Make 3 more batches. Add sugar to taste if desired and serve over ice.
