KITCHEN TIP: To add a citrusy salt rim to your Paloma, stir together 2 tablespoons kosher salt, 1 tablespoon sugar, 1 teaspoon grapefruit zest, and ½ teaspoon lime zest, until well combined. Lightly wet rims of serving glasses with water or citrus juice. Dip one side of each glass rim in salt mixture. Add garnishes, as desired.
