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

What each ingredient does

Peanuts
Provide the main body and nutty flavor of the filling.
Butter
Binds the chopped peanuts into a spreadable paste and adds richness.
Mustard
Adds sharp acidity that contrasts with the rich peanut paste.

The step that matters

Chopping the peanuts finely. Fine pieces blend with the melted butter into a smooth, spreadable paste. Coarse pieces stay separate, so the filling can crumble or tear the bread.

Swap the mustard

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

  1. Potatofits better
  2. Capsicumfits better
  3. Asparagusfits better
