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

What each ingredient does

Eggs
Provide the main body and protein of the dish, sliced over the toast.
Milk
Forms the liquid base of the sauce that is thickened into a smooth coating.
Flour
Thickens the milk as its starch swells when heated, giving the sauce body.
Butter
Adds fat and richness, and blends with the flour to help it mix smoothly into the milk.
Light bread
Forms the base that holds the eggs and sauce.

The step that matters

Cook the sauce until thick, stirring constantly. Flour thickens milk only as its starch swells with heat. Stopping the stirring lets the sauce scorch on the pan base or form lumps, so it may not reach a smooth, even thickness.
