2 1/2 cups seedless (or seeded) watermelon, cut into 1-inch cubes, rind discarded before measuring 3 tablespoons freshly squeezed lime juice 4 ounces tequila 2 ounces orange flavored liqueur 1 1/2 cups ice Lime wheel or watermelon wedge, for garnish
Put cut watermelon in a plastic bag and place in freezer for a minimum of 2 hours. (If time does not permit this step, add a few extra ice cubes when blending, the difference is not that significant.) Stuff all ingredients into a blender and puree until smooth. Garnish rim of glass with a lime wheel or a watermelon wedge and serve immediately.
