Why it works: Brandy and rum 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 emulsify and thicken the drink; whites add a light, foamy topping.
- Milk
- Provides the liquid base and creamy body of the drink.
- Sugar
- Sweetens the drink and balances the alcohol.
- Brandy
- Adds spirit strength and warm flavour to the drink.
- Jamaica rum
- Adds deeper, molasses-like aroma alongside the brandy.
The step that matters
Stir gently with a small spoon to create nuggets of egg white.. Beaten egg whites are a fragile foam. Gentle stirring breaks them into small pieces that stay suspended, while vigorous stirring deflates them and the topping turns flat and watery.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, milk, sugar, brandy, rum):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Clovefits less well
Fit is the average pairing score against egg, milk, sugar, brandy, rum. Candidates are from the same food group and used in at least 100 recipes.
