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 Water is best made the same day it is served, but it can be made a few hours ahead of time. Please note this fresh drink is perishable after 2 days.Refrigeration: You can keep this agua fresca in the refrigerator for up to two days, and it will still taste fresh.
