Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when heated, forming the soft, creamy body of the topping.
- Butter
- Enriches the eggs and coats the pan, adding richness and flavor.
- Bread
- Provides a crisp, toasted base that holds the egg topping.
The step that matters
Stirring the eggs in the hot pan. Eggs proteins set quickly over heat. Stirring keeps curds soft and moist; if left still or overcooked they turn dry and rubbery.
