Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a custard that binds the coating and gives the toast a tender interior.
- Milk
- Adds moisture to the egg mixture, keeping the coating soft and custardy.
- Bread
- Soaks up the egg mixture and provides the structure that holds the dish together.
- Butter
- Adds fat that browns the surface and gives a rich flavor.
The step that matters
Turn the bread when it is light brown. Soaked bread is fragile, so flipping it too early can tear it. Waiting until the surface is light brown lets the coating set and form a crust that holds together.
