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

What each ingredient does

Eggs
Thicken the custard and add richness and structure to the ice cream.
Milk
Forms the liquid base that becomes the custard and the frozen body of the ice cream.
Sugar
Adds sweetness and keeps the frozen ice cream softer rather than rock hard.
Cocoa
Provides the chocolate flavor and deep color of the ice cream.

The step that matters

Cook the cocoa mixture until thick and glossy. Cocoa does not dissolve in cold liquid and clumps easily. Cooking it fully hydrates the cocoa particles, smooths out lumps, and reduces the raw, bitter taste of unheated cocoa, so the final base is smooth and well flavored.

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.
