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 dip and add richness and color to the toast.
Egg whites
Whipped to a froth, they add lightness and body to the lemon sauce.
Sugar
Sweetens the lemon sauce and helps stabilize the beaten egg whites.
Lemon juice
Adds acidity and bright flavor that balances the sweetness of the sauce.
Baker's bread
Soaks up the egg mixture and fries to a golden, crisp-edged slice.

The step that matters

Beating the egg whites to a froth. Egg whites must be beaten until foamy so they hold air. Adding the sugar and liquids after that helps the sauce stay light rather than collapsing into a thin, watery mixture.

Swap the lemon
