Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Gentle heat sets the white while the yolk stays soft and runny.
- Bread
- Toasted slices give a sturdy base that holds the soft egg.
- Butter
- Adds richness and fat to the warm toast.
The step that matters
Cook the eggs without boiling. Keep the water on low heat, below a boil. Vigorous boiling jostles the eggs, can crack the shells, and firms the yolk through, so the eggs lose the soft, runny centre this dish depends on.
