Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Its drier structure soaks up the custard without collapsing into mush.
- Eggs
- They set into a custard that coats the bread and firms up when cooked.
- Milk
- It thins the egg mixture so it soaks into the bread evenly and stays moist.
- Butter
- It adds fat for frying and helps the outside brown and taste rich.
The step that matters
Soaking and frying the bread. Soak the slices just long enough to saturate them, or they will fall apart. Fry over moderate heat so the custard sets inside before the outside over-browns.
