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

What each ingredient does

Eggs
Whites beaten stiff give lightness, while the yolks thicken the sauce as it cooks into a custard.
Flour
Starch thickens the melted butter and milk into a smooth, stable cream sauce.
Milk
Forms the liquid base of the cream sauce, giving it body and a mild sweetness.
Butter
Adds fat and richness, and helps the flour cook smoothly into the sauce.

The step that matters

Fold the egg mixture into the cream sauce and cook until the egg is firm like custard.. Egg proteins set when heated, so the mixture must be cooked gently until thickened. Overheating can curdle the eggs and make the custard grainy, while underheating leaves it runny.
