Notes
My Top Tip♡ Make sure both the watermelon and the water are cold, so you can serve this refreshing beverage immediately after blending.Make-Ahead & StorageMake-Ahead: This Watermelon Agua Fresca tastes best the day it is made, but can be prepared a few hours ahead and refrigerated until serving.Refrigeration: Store leftovers in the refrigerator for up to 2 days. Stir before serving, as natural separation may occur.
