Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Provide the crunchy, chopped filling that gives the sandwich its body.
- Mayonnaise
- Moistens the chopped nuts and binds them into a spreadable filling.
- Butter
- Coats the bread to add richness and keep it from soaking up the filling.
