What Is Rum Sour?

The classic Whisky Sour cocktail blends whisky, lemon juice, syrup, and egg white for a balanced mix of citrus, sweetness, and creaminess.

Rum Sour is a playful twist on the Whisky Sour, using rum instead of whisky. Our Rum Sour adds a drop of Angostura bitters and a float of Lillet Rouge, adding an elegant French touch. And the Lillet Rouge float on our Rum Sour not only looks beautiful but also adds a delightful sweetness. With its refreshing yet subtly warm character, Rum Sour is perfect on a sunny day as well as a cozy evening. Cheers!

Angostura: Angostura bitters adds extra depth and bitter complexity and enhances the rum and Lillet Rouge.
Lillet Rouge: We add Lillet Rouge to our Rum Sour for its distinctive flavors, which include notes of fruits, spices, and herbs.
Rum: We use a good-quality dark rum for its rich flavor, which pairs perfectly with the zestiness of Rum Sour.
Egg: As we use raw egg, ensuring it’s super fresh is crucial!
Lemon: Fresh lemon juice makes all the difference.
Maple Syrup: Maple syrup has a rich, complex sweetness that adds depth and a hint of natural earthiness.

How To Make Rum Sour

3 steps

Shake!

Firstly, combine rum, lemon juice, maple syrup, a drop of Angostura bitters, and the egg white in a shaker. Close the shaker tightly and shake vigorously for about 30 seconds.

Pour

Now grab a nice glass and add ice cubes. Then carefully pour the shaker's mix over the ice cubes - pour gently to maintain the drink's texture and presentation. Finally, slowly pour Lillet Rouge over the back of a spoon to create a nice red Lillet float.

Finish!

Finish your Rum Sour with a sprig of fresh thyme or a twist of lemon peel for a perfect cocktail experience!

Serving Tips & Pairings

Garnish: Besides thyme or lemon peel, you can experiment with other garnishes like fresh mint, a twist of orange peel, some fresh lavender flowers or a maraschino cherry…
Roasted nuts: Cocktails and nuts? Definitely!
Appetizer: Scampis Diaboliques make a great and fancy savory appetizer with Rum Sour. Or try a slice of Mazapán dipped in chocolate!

Substitutions & Variations

Sweetener: Swap maple syrup for simple syrup or honey.
Lemon: While lemon juice is traditional, you can also experiment with lime juice or tangerine juice for a citrus twist.
Lillet float: Instead of Lillet Rouge, you can try vermouth or red whine, like Cabernet Sauvignon for a different float on top!
Vegan: Just leave out egg white!
