Overview

What this drink is like

The first sip is thick and sweet, tasting of caramel and warm rum. The egg gives it a custardy middle that coats your tongue, while the nutmeg on top adds a dry, woody spice. It finishes warm and lingering, like a sip of liquid dessert.

Who will like it

This is for people who like rich, dessert-style drinks such as Eggnog or Brandy Alexander.

When to drink

Drink this at the end of a meal or on a cold evening when you want something warming and filling.

Ordering tip

Ask the bartender to use a dark Jamaican rum if you want a bigger, funkier flavor, or a aged Demerara rum for a smoother, caramel-heavy drink.

Recipe

Shaken · Sour · equal parts on Dark Rum. Aged or dark rum works best; Jamaican or Demerara add great depth

Before you start

Pull a fresh egg from the fridge and give it a sniff to make sure it's good. Get your ice ready—you will need a lot, since you have to shake this longer than a normal drink to cook the egg into a foam.

Steps

1
Crack one whole egg into your empty shaker. Add 60ml dark rum, 15ml simple syrup, and 2 dashes of Angostura bitters. Don't add the ice yet.
!Adding ice before the first shake makes it much harder to break up the egg yolk.
2
Seal the shaker and shake it hard for about 10 seconds without any ice inside. This dry shake whips the egg white into a thick foam and mixes the yolk completely. You will hear the liquid sloshing heavily against the walls.
~10s
!Shaking too gently here leaves chunks of yolk floating in the drink.
3
Open the shaker and fill it to the top with ice cubes. Seal it tight again and shake hard for another 12 to 15 seconds. Keep going until the outside of the metal shaker feels freezing cold and frosty to the touch.
~15s
!Stopping too early leaves the drink thin and warm instead of thick and chilled.
4
Pop the lid off and fit a Hawthorne strainer over the mouth of the shaker. Pour the drink through the strainer into a chilled sour glass or small wine glass. The liquid should look pale, creamy, and topped with a good finger of foam.
!Pouring too fast can break the foam and leave you with a flat top.
5
Take a whole nutmeg and a microplane, and grate a dusting of fresh nutmeg right over the top of the foam. The heat from the drink will carry the scent up immediately. Serve it right away while it is still cold.
!Using pre-ground nutmeg tastes flat and dusty compared to fresh grated.

Serve

Serve it straight up in a chilled sour glass with no ice. The drink should be thick and pale, capped with a layer of foam and a dusting of fresh nutmeg.

History

Origin

Flips originated in the late 1600s as hot drinks made of ale, sugar, and rum, heated with a red-hot iron poker. By the 19th century, the recipe dropped the beer and poker, shifting to a cold mixture of spirit, egg, and sugar that is still made today.

Era: 1690s
Confidence

The Rum Flip is a well-documented historical cocktail, but exact proportions vary widely across old bar manuals; this spec uses a modern, balanced ratio.

Tips & pitfalls

What works at home and what to skip when making this drink.

Tips

Worth knowing before you pour

Use the freshest egg you can find to avoid any off smells.
Always do the dry shake first to get the thickest foam.
Grate the nutmeg right over the glass so the oils hit the foam.
Chill your serving glass in the freezer for 10 minutes before making the drink.

Avoid

Common mistakes

Skipping the dry shake leaves you with a watery, broken texture.
Using pre-ground nutmeg makes the drink taste dusty and flat.
Shaking with ice before the dry shake prevents the egg from whipping up.
