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

What each ingredient does

Hard-boiled eggs
Form the main filling, providing body and richness to the sandwich.
Buttered bread
Holds the filling and gives the sandwich its structure, with butter adding fat.
Pepper
Adds a sharp aroma that contrasts with the rich, mild egg.

The step that matters

Handle the grated egg gently. Crushing or pressing the grated egg packs it into a paste that releases moisture and can make the bread soggy. Keeping the grated egg loose keeps the filling light and evenly textured.
