A gift from our Italian friends, Gelo di Melone is very light, not too sweet, and very easy to make. This 3-ingredient Watermelon Pudding is made with fresh watermelon, sugar, and corn starch - simple and light. Fresh watermelon has a high water content, so this Watermelon Pudding is softer than a milk-based pudding and tastes wonderful on a hot summer's day.
