Watermelon gives the Silver Coin Margarita, from Austin's Fonda San Miguel, its refreshing kick. We recommend using Herradura Silver Tequila.
FOR THE WATERMELON-INFUSED TEQUILA:
1 medium-size seedless watermelon
1 750-ml bottle of silver tequila
FOR THE MARGARITA:
4 oz. of the watermelon-infused tequila
2 oz. frozen limeade
2 cubes of the infused watermelon
1 1⁄2 oz. Cointreau
1. For the infused tequila, cut a watermelon into 1" cubes (rind removed) until you have roughly 2 lbs. of fruit. Transfer to a glass jar, pour in tequila, seal jar, and let steep for 2 days.
2. To make drinks, combine the watermelon-infused tequila, 2 cups crushed ice, frozen limeade, infused watermelon, and Cointreau in a blender. Purée until slushy. Garnish with watermelon wedges.
