What each ingredient does
- Bread
- Provides a crisp, browned base that holds the egg and absorbs the butter.
- Melted butter
- Adds richness and flavour and moistens the toast surface.
- Eggs
- Set into a soft, tender topping that thickens as it cooks.
The step that matters
Cooking the eggs in simmering water. Water that is too hot or boiling makes egg whites feather and tear, while gentle simmering lets the whites coagulate around the yolk so the egg stays intact.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
