These frozen fruit cubes are subtly sweet, completely refreshing and--best of all--require only one ingredient. From sparkling water to sangria, they're a no-brainer way to upgrade your summer drinks.

Put the baking sheet in the freezer for about three hours, or until frozen. Then plop the watermelon cubes into a plastic bag to store them.
