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

What each ingredient does

Bread
Provides the structure that holds the sandwich together and the soft base for the fillings.
Butter
Adds fat and richness to the bread, carrying flavor and keeping it from soaking up the spreads.
Tomato paste
Concentrates tomato flavor and adds savory, slightly sweet depth to the sandwich.
