Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Set the custard and bind it to the bread, giving structure and richness.
Milk
Forms the liquid base of the custard, adding moisture and softness.
Flour
Thickens the milk and egg mixture so it coats the bread smoothly.
Bread
Soaks up the custard, then browns in the pan for a crisp outer layer.

The step that matters

Cook the milk and egg mixture until smooth. Eggs can scramble if overheated, and flour can leave lumps if not stirred well. Cooking gently in a double boiler and keeping the mixture moving keeps it smooth and evenly thickened for coating the bread.
