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
- Egg yolk
- Adds richness and emulsifies the milk, giving the drink a smooth, creamy body.
- Egg white
- Whipped to stiff peaks, it adds a light, airy foam that lifts the texture.
- Milk
- Forms the liquid base, adding moisture and creaminess to the drink.
- Sugar
- Sweetens the base and helps stabilise the beaten yolk.
The step that matters
Folding in the beaten egg white. Stiff egg white foam holds air only if it is folded gently. Stirring or mixing it hard deflates the foam, so the eggnog loses its light texture and separates.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, milk, rum, brandy):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Clovefits less well
Fit is the average pairing score against egg, sugar, milk, rum, brandy. Candidates are from the same food group and used in at least 100 recipes.
