Citrus Rum Fizz

**Description:** A refreshing and bubbly cocktail that combines the complex bittersweet flavor of Aperol with the bright acidity of fresh citrus, a smooth and frothy texture from egg whites, and the warmth of rum, all topped with the effervescence of sparkling water. **Ingredients:** - 2 oz Rum (preferably a light or aged rum for complexity) - 1 oz Aperol - 1 oz Fresh orange juice (strained to remove pulp) - 1/2 oz Fresh lemon juice - 1 oz Egg whites (about the white from one large egg) - Sparkling water to top off - Ice cubes - Orange twist and a cherry for garnish (optional) **Instructions:** 1. In a cocktail shaker, combine the rum, Aperol, fresh orange juice, lemon juice, and egg whites. 2. Dry shake (without ice) vigorously for about 15 seconds to emulsify the egg white. 3. Add ice to the shaker and shake again until well-chilled. 4. Strain into a chilled highball glass filled with ice. 5. Gently top off with sparkling water, allowing a foam to form on top. 6. Garnish with a twist of orange peel and a cherry, if desired. **Glass:** Highball Glass
