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 soak and help the bread brown and set when fried.
- Stale sweet milk
- Soaks into the bread to give a moist, custardy interior.
- Egg whites
- Whipped to a froth to lighten the lemon sauce.
- White sugar
- Sweetens the lemon sauce and adds body when whipped with the whites.
- Lemon juice
- Adds acidity that brightens the sweet sauce.
The step that matters
Fry the dipped bread until golden brown. Bread soaked in egg and milk browns quickly in the fat and can scorch on the outside before the centre is cooked. Moderate heat lets the custard set through while the crust turns golden.
Swap the lemon
How well each one fits the dish's main ingredients (egg, milk, bread, butter, sugar):
- Vanillafits better
- Figfits better
- Peachfits about as well
- Lemonthe original
Fit is the average pairing score against egg, milk, bread, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
