Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide body and a thick, frothy texture to the drink.
- Granulated sugar
- Adds sweetness and helps the eggs hold a smooth, stable foam.
- Rum
- Adds the main alcoholic flavor and warming aroma.
- Nutmeg
- Adds a warm, aromatic spice finish on top.
The step that matters
Stirring the boiling water into the egg mixture. Hot liquid partly cooks egg proteins, so pouring it in too quickly or without constant stirring can curdle the eggs and leave the drink lumpy instead of smooth.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, rum):
- Cinnamonfits about as well
- Nutmegthe original
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against egg, sugar, rum. Candidates are from the same food group and used in at least 100 recipes.
