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

What each ingredient does

Butter
Provides fat that makes the filling rich and gives it a creamy, spreadable body.
Confectioner's sugar
Sweetens the filling and dissolves smoothly into the creamed butter for a fine texture.
Powdered cocoa
Adds chocolate flavor and deep color to the filling.
Very strong coffee
Deepens the chocolate flavor and adds a mocha aroma with a hint of bitterness.

The step that matters

Cream together the butter and confectioner's sugar. Beating butter with sugar traps air and dissolves sugar into the fat, producing a light, smooth base. If the butter is too cold or too soft, the mixture can stay grainy or turn greasy.

Swap the cocoa

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

  1. Cocoathe original
  2. Almondfits about as well
  3. Hazelnutfits less well
  4. Chestnutfits less well

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