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

What each ingredient does

Peanuts
Provide the main filling, adding texture and a nutty flavour.
Butter
Binds the chopped peanuts and adds fat and richness to the filling.
Bread
Forms the structure and holds the filling in each sandwich.
Cheese
Adds a savoury flavour and extra richness to the sandwich.

The step that matters

Mix the chopped peanuts with the butter until well combined.. Thorough mixing spreads the fat evenly through the peanuts, so the filling spreads smoothly and avoids dry or greasy patches.

Swap the peanut

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

  1. Lima beansfits better
  2. Pecansfits better
  3. Walnutfits about as well
  4. Peanutthe original

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