- 1 egg white or aquafaba
- ice cubes for shaking
- lemon slice or lime wheel, for garnish
Instructions
- Add rum, lemon juice, simple syrup, and egg white (or aquafaba) to a shaker.

Notes
Use aged rum for deeper flavor or white rum for a crisper drink. Aquafaba is a vegan alternative to egg white. Fresh lemon juice is essential—never use bottled. Chill glassware for a smoother finish.
