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

What each ingredient does

White bread: Provides the soft base and structure that holds the filling together.
Softened butter: Adds fat and richness and helps keep the bread from soaking up moisture from the filling.
Cold boiled or roasted chicken: Supplies the main protein and the bulk of the sandwich filling.
Mayonnaise dressing: Adds moisture, fat, and a creamy texture that binds the chicken.
