The Malibu Rum Sour Cocktail combines the smooth coconut flavor of Malibu rum with fresh lemon juice, simple syrup, and an optional egg white for a bright, sweet-tart sip. It’s light, refreshing, and quick to make—perfect for summer or any easy happy hour.
Add Malibu rum, lemon juice, simple syrup, and egg white (if using) to a cocktail shaker.
Fill the shaker about three-quarters with ice.
Shake firmly for 15–20 seconds, until the outside is icy cold.
Strain into a rocks glass over fresh ice.
Top with a lemon wheel or cherry for garnish.
Notes
Fresh lemon juice gives the brightest flavor. Add more syrup for a sweeter drink, or extra lemon juice for a more sour profile. Egg white adds a silky texture but is optional. Garnish with lemon or cherry for aroma and a polished look.
