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 ↓

Ingredients
Directions
Make the base
Beat the egg yolks in a bowl until smooth.
Add 1 tablespoon of sugar to each egg yolk and mix until bubbles appear.
Slowly pour in the brandy while stirring continuously.
Gradually add the milk while stirring, then add the rum to taste.
Finish and serve
In a separate bowl, beat the egg whites until stiff peaks form.
Top the eggnog with the whipped egg whites and sprinkle with nutmeg before serving.

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 body, while whipped whites give a light, airy topping.
- Sugar
- Adds sweetness that balances the alcohol and the richness of the yolks.
- Brandy
- Contributes its warm, fruity aroma and flavor to the drink.
- Milk
- Provides the liquid base and a creamy, smooth texture.
- Rum
- Adds depth of flavor and aroma, added to taste.
The step that matters
Beat the egg whites to stiff peaks. Whites beaten until stiff hold air and sit lightly on top. Overbeaten whites turn dry and grainy and tend to weep liquid, so stop once the peaks stand upright.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, brandy, rum, milk):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Clovefits less well
Fit is the average pairing score against egg, sugar, brandy, rum, milk. Candidates are from the same food group and used in at least 100 recipes.
