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

What each ingredient does

Walnuts
Add crunch and a rich, slightly bitter nuttiness to the filling.
Olives
Contribute salty, briny flavor that contrasts with the fat and bread.
Mayonnaise dressing
Adds moisture and fat, binding the nuts and olives and keeping the bread from drying.
Butter
Adds richness and flavor to the bread and helps it brown lightly on the outside.
