Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set proteins form the soft, cooked main element of the dish.
- Bread
- Provides a crisp, toasted base that holds the cooked egg.
- Butter
- Adds richness and fat, carrying flavour over the toast.
The step that matters
Cook until the egg white is set. Egg white begins to set at moderate heat and firms as proteins coagulate. Stopping too early leaves runny whites, while overcooking toughens the egg, so check the white rather than the yolk.
