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

What each ingredient does

Egg yolks
Enrich the milk mixture and help the bread soak up custard for a rich texture.
Sweet milk
Provides moisture and liquid that soaks into the bread.
Baker's bread
Forms the base that absorbs the egg mixture and fries to a golden crust.
Egg whites
Whipped to a froth, they lighten the sauce and give it a airy, foamy body.
White sugar
Adds sweetness and stabilizes the whipped egg whites in the sauce.
Lemon juice
Adds acidity and bright flavor to the sauce.

The step that matters

Frying the dipped bread in hot butter. Bread that is too cold or fried too slowly absorbs excess fat and turns greasy, while overly hot butter can burn before the inside is soaked through. Medium-high heat gives an even golden-brown crust.
