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 add richness and colour to the bread coating.
- Egg whites
- Whipped to a froth, they add airy lightness to the lemon sauce.
- Sweet milk
- Soaks into the bread, moistening it before frying.
- White sugar
- Sweetens the lemon sauce and helps stabilise the whipped egg whites.
- Lemon juice
- Adds acidity that balances the sweetness of the sauce.
The step that matters
Fry the dipped bread slices in hot melted butter until golden brown.. If the butter is not hot enough, the bread absorbs fat and turns greasy instead of browning. Enough heat sets the egg coating quickly and creates a golden crust.
