Volcan tequila 1 oz. grapefruit juice 3⁄4 oz. lime juice 3⁄4 oz. simple syrup 1⁄2 oz. Tattersall Bitter Orange liqueur (or see suggested replacements above) 4 dashes grapefruit bitters Fever-Tree Sparkling Pink Grapefruit Grapefruit peel, for garnish Add all ingredients in a Boston shaker, excluding the grapefruit soda and peel. Add ice, shake, and strain over ice into a Collins glass. Top with Fever-Tree Sparkling Pink Grapefruit.
