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):
- Lima beansfits better
- Pecansfits better
- Walnutfits about as well
- 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.
