Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and body, and help emulsify the drink into a smooth, creamy texture.
- Egg whites
- Whipped to stiff peaks, they add a light, airy foam that lifts the texture.
- Powdered sugar
- Sweetens the base and dissolves easily into the beaten yolks.
- Rum
- Adds aroma and flavor, and its alcohol helps keep the drink stable.
- Rich milk
- Provides the liquid base and adds moisture and creaminess.
The step that matters
Folding in the egg whites. Stiff whites hold air only if they are not overbeaten or deflated. Folding gently, rather than stirring, keeps the foam light so the eggnog stays fluffy instead of turning dense or watery.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, rum, brandy, milk):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Clovefits less well
Fit is the average pairing score against egg, sugar, rum, brandy, milk. Candidates are from the same food group and used in at least 100 recipes.
