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

What each ingredient does

Fresh roasted peanuts
Provide the main nutty flavor and the body of the filling once ground.
Oil mayonnaise
Adds fat and moisture so the ground peanuts form a spreadable paste.
Cream
Adds moisture and fat, making the alternative filling softer and smoother.
Butter
Adds fat and richness, helping the alternative filling spread and hold together.

The step that matters

Grind or chop fresh roasted peanuts finely.. Fine grinding releases the peanuts' oils and breaks them into small particles, creating a smooth paste that spreads easily and holds together. Coarse pieces tend to tear the bread and fall out of the sandwich.

Swap the peanut

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

  1. Almondfits better
  2. Pecansfits better
  3. Lima beansfits better
  4. Peanutthe original

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