Why it works: Rum and brandy are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,058 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and thickness, while beaten whites add a light, airy texture.
- Sugar
- Adds sweetness and balances the strong flavor of the alcohol.
- Rum
- Adds aroma and a warm, distinct flavor to the base.
- Brandy
- Adds aroma and depth of flavor alongside the rum.
- Cream
- Adds fat for a smooth, rich mouthfeel and body.
- Milk
- Adds moisture and creaminess, thinning the base to a pourable texture.
The step that matters
Pour boiling water over the egg whites to partially cook them.. Heat partly sets the egg white proteins, which stabilizes the foam. Too much heat or too long a contact time sets the whites into lumps, so they will not fold smoothly into the mixture.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, rum, brandy, cream):
- Nutmegthe original
- Cinnamonfits about as well
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against egg, sugar, rum, brandy, cream. Candidates are from the same food group and used in at least 100 recipes.
