What each ingredient does

Eggs: Set into a tender structure as the whites firm while the yolks stay soft.
Butter: Adds richness and moisture, coating the egg and softening its flavour.
Fine toasted bread crumbs: Absorb moisture and give a light, lightly toasted crust on the cup and egg surface.

The step that matters

Placing the cups in boiling water until the whites are solid. Egg white begins setting around 60°C and firms as it heats. If the water is too cool the whites stay runny, and if the cooking runs too long the yolks can overcook and turn firm and chalky.
