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

What each ingredient does

Coffee beans
Form the roasted product; their sugars and oils brown and develop flavor during roasting.
Butter
Adds a small amount of fat that gives the roasted beans a richer, rounder mouthfeel.

The step that matters

Stirring constantly while the beans brown. Coffee beans roast unevenly against hot metal. Constant stirring spreads the heat so the beans brown evenly and do not scorch, which would leave a bitter, burnt taste.

Swap the beans

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

  1. Cocoafits better
  2. Pecansfits better
  3. Hazelnutfits better
  4. Beansthe original

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