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

What each ingredient does

Prepared nuts
Pound into an oily paste that forms the base of the mixture, giving flavor and body.
Powdered sugar
Sweetens the paste and helps it blend smoothly into the cocoa.
Prepared cocoa
Provides the chocolate flavor and makes up the bulk of the paste.

The step that matters

Pounding until fully combined. If the sugar and cocoa are not pounded long enough, the mixture stays gritty and the sugar does not dissolve evenly into the fats released by the nuts and cocoa, so the paste feels sandy rather than smooth.

Swap the cocoa

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

  1. Pistachiofits better
  2. Almondfits better
  3. Brazil nutfits better
  4. Cocoathe original

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