Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Whipped with sugar, they add foamy body and a creamy, rich texture to the drink.
Powdered sugar
Sweetens the drink and dissolves easily into the beaten eggs.
St. croix rum
Provides the main spirit flavor and warmth in the drink.
Boiling water
Heats the mixture and loosens it so it blends smoothly with the eggs and rum.

The step that matters

Pour the mixture back and forth between two hot pitchers. Pouring aerates the mixture and blends it evenly while keeping it hot. Hot vessels help the drink stay warm when served, and the mixture should be served immediately so the foam doesn't collapse.

Swap the nutmeg

How well each one fits the dish's main ingredients (egg, sugar, rum):

  1. Cinnamonfits about as well
  2. Nutmegthe original
  3. Gingerfits less well
  4. 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.
