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

What each ingredient does

Hard boiled eggs
Provide the main filling, adding substance and a soft, creamy texture.
Bread
Forms the structure that holds the filling and keeps the sandwich together.
Butter
Adds richness and fat, and keeps the bread from soaking up moisture from the filling.
Watercress
Adds a fresh, peppery bite that contrasts with the rich eggs and butter.
