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

What each ingredient does

Eggs
Beaten eggs set the custard into a soft, sliceable texture as they cook.
Cocoa
Provides the chocolate flavor and deep color that define the custard.
Milk
Forms the liquid base that carries the cocoa and gives the custard its richness.
Sugar
Adds sweetness to balance the bitter chocolate flavor.

The step that matters

Bake until set. Eggs set through gentle heat, and overbaking causes them to curdle and turn grainy, so the custard should be removed once just firm.

Swap the cocoa

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

  1. Pecansfits about as well
  2. Almondfits about as well
  3. Cocoathe original
  4. Walnutfits about as well

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