Fluffy Duck is a classic cocktail that combines the flavors of orange, lemon, and rum with the creamy richness of egg white. This refreshing and frothy drink is perfect for a summer gathering or a cozy night in. The combination of citrus and rum creates a balanced and tangy flavor, while the egg white adds a velvety texture. Serve it chilled in a cocktail glass and garnish with a slice of orange for a delightful presentation.
