Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind to the bread and set when cooked, forming the custard coating.
- Bread
- Absorbs the egg mixture and provides the structure that holds the dish together.
- Butter
- Adds fat for richness and helps the surface brown in the pan.
The step that matters
Turning the bread when it is light brown. Turning too early tears the soaked bread, while waiting too long over medium heat can scorch the coating before the egg centre sets.
