The Rum Sour is a classic cocktail that dates back to the 1800s. It is believed to have originated in the Caribbean, where rum was plentiful and citrus fruits were used to prevent scurvy among sailors. The Rum Sour quickly gained popularity and became a staple in bars around the world.

  • The Rum Sour is a variation of the classic Whiskey Sour.
  • It is said to have been a favorite among pirates and sailors.
  • The cocktail has evolved over time, with many variations and twists on the original recipe.

How Rum Sour Tastes?

The Rum Sour is a well-balanced cocktail with a tangy, citrusy flavor that is complemented by the sweetness of the rum. It has a smooth, velvety texture and a slightly tart finish.

Interesting facts about Rum Sour

  • The Rum Sour is sometimes called a 'Daiquiri Sour' due to its similarities with the classic Daiquiri.
  • The cocktail is traditionally made with dark rum, but can also be made with white or spiced rum for a different flavor profile.
  • The use of egg white in the recipe creates a frothy, creamy texture that adds to the overall experience of the drink.


Dark Rum

*Used for its rich, complex flavors that can range from sweet caramel to spicy notes. 2 oz is just the right amount to get a strong rum flavor without overpowering the drink. Without it, you'd just have a sad, non-alcoholic lemonade.

Lemon Juice

*Bright and tart, the 1 oz lemon juice provides the 'sour' to balance the sweet. Too little, and the cocktail is cloying; too much, and you'll pucker more than a grandma's kiss.

Alex Green

Simple Syrup

*Sweetness to complement the sour, the 0.5 oz of simple syrup rounds out the sharp edges of the lemon juice. If omitted, it's like a joke without a punchline—not very sweet.

Emma Rose

Egg White

*For texture, the egg white gives the cocktail a silky smooth body and a fancy frothy top hat. Without it, the drink loses its sophistication and feels flat. If you're vegan, aquafaba can strut down the same runway.

Mary Mitkina

Aromatic Bitters

*A mere two dashes of this potent potion add complexity and depth, enhancing the cocktail's flavor like a sprinkle of magic. Leave it out, and you'll miss the whisper of spice that says, 'I'm more than just a pretty face.'

Alex Green

Orange Wheel

*The eye eats first, and the orange wheel is there to please. It adds a hint of citrus aroma which subtly nudicates the senses and hints at the flavors to come.

Emma Rose

Maraschino Cherry

*This is the cherry on top, literally. It's a sweet treat that'll be waiting for you at the end like a goodnight kiss after a first date. It rounds the drink visually and offers a final, sweet bite.

Pro Tips

  • Dark Rum: For a richer, deeper flavor, try using a high-quality aged rum.
  • Shaking: Shake the cocktail until the shaker becomes frosty. This ensures that the cocktail is well-chilled.
  • Egg White: For a vegan option, you can use aquafaba (chickpea water) as a substitute for egg white to create the frothy texture.

Perfect Pairings


  • Cheese Platter: A selection of sharp cheeses can complement the sweet and sour notes of the Rum Sour.
  • Smoked Salmon: The oily richness of smoked salmon pairs beautifully with the acidity of the lemon juice.
  • Nuts: Almonds or cashews offer a contrast in texture and a grounding earthiness.

Main Courses

  • Grilled Pork: The smokiness of grilled pork finds a delightful counterpart in the rum's caramel notes.
  • Jerk Chicken: The spices in jerk seasoning match well with the complexity of the dark rum.
  • Seafood: Lighter seafood dishes like grilled shrimp can balance the weight of the cocktail without overwhelming the palate.


  • Lemon Tart: Echo the citrus in the drink with a tangy lemon tart.
  • Chocolate Mousse: A luxurious mousse plays well with the deep flavors of dark rum.
  • Fruit Salad: A fresh fruit salad with tropical fruits draws out the rum's inherent sweetness.
