What each ingredient does
- Egg
- Its proteins set when heated, forming the soft, cooked white and runny yolk on the toast.
- Bread
- Browning gives the toast a crisp, toasted flavour and a sturdy base for the egg.
- Butter
- Adds fat and richness, carrying flavour and softening the toast's surface.
The step that matters
Letting the white set before lifting the egg. Egg white begins to set at around 60°C and firms as it heats. Lifting too early can tear the delicate white apart, so wait until it has firmed before using the skimmer.
