“Summer’s best flavours get frosty in the cocktail we serve at all our backyard shindigs. We mix sun-ripened watermelon and our favourite tequila with just the right amount of ice for a thick and boozy sipper that’s perfect when we’re grilling and chilling.” —Alicia Cummings, Marshalltown, Iowa
Cut 1 lime into 12 wedges; reserve for garnishes. If desired, coat the rim of each glass with sugar: Cut remaining lime into wedges. Using these wedges, moisten the rims of 12 margarita or cocktail glasses. Sprinkle sugar on a plate; hold each glass upside down and dip rim into sugar. Discard remaining sugar.
Place half the watermelon in a blender; cover and process until pureed (this should yield 3 cups). Add half each of the following: ice cubes, tequila, Triple Sec and lime juice. If desired, add sugar to taste. Cover and process until blended.
Serve in prepared glasses. Repeat with remaining ingredients. Garnish with reserved lime wedges.
