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.
