What each ingredient does

Eggs
Form the main filling, giving the mashed mixture body and richness.
Butter
Adds fat and flavour to the filling and coats the bread for a richer taste.
Bread
Forms the outer layers and holds the mashed egg filling in place.

The step that matters

Boil the eggs for 30 minutes. Boiling long enough sets the yolks fully firm so they mash evenly. Overcooking can leave a greyish-green ring around the yolk, caused by a reaction between sulfur in the white and iron in the yolk, and makes the filling dry.
