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

What each ingredient does

Eggs
Provide the main filling, with a firm, sliced texture once hard-boiled.
Butter
Adds fat and richness to the bread and carries flavour into the sandwich.
Bread
Provides the structure that holds the sliced egg filling together.

The step that matters

Cool the eggs completely before slicing. Eggs that are still warm are soft and crumble or smear when sliced. Full cooling firms the whites and yolks so the slices stay neat and hold their shape in the sandwich.
