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

What each ingredient does

Cocoa shells
Provide the chocolate-like flavor and color of the drink.
Egg white
Coagulates when heated and traps fine particles so the liquid can be clarified.
Vanilla extract
Adds aroma that rounds out the cocoa flavor.
Cream
Adds fat and richness, softening the drink's bitterness.
Sugar
Adds sweetness to balance the bitter cocoa flavor.

The step that matters

Boil for 10 to 15 minutes. Heat must be held long enough for the egg white to set and trap fine particles. Boiling too briefly leaves the liquid cloudy after straining, while handling the cloth roughly can push particles back through.

Swap the cocoa

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

  1. Almondfits better
  2. Chestnutfits better
  3. Hazelnutfits better
  4. Cocoathe original

Fit is the average pairing score against egg, vanilla, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
