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

What each ingredient does

Eggs
Coagulate when heated, setting the custard into a firm but tender structure.
Milk
Supplies the liquid that sets with the eggs into a soft, creamy texture.
Sugar
Adds sweetness and softens the flavour of the set custard.

The step that matters

Steam until firm, over gently boiling water. Egg proteins set as they heat, and excess heat makes them tighten further, causing the custard to become rubbery, curdled or weep liquid. Gentle heat keeps the texture smooth and even.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Gingerfits less well
  4. Peppermintfits less well

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