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

What each ingredient does

Eggs
Yolks enrich the dip and help the bread brown; whites whipped to a froth lighten the sauce.
Sweet milk
Moistens the bread so it soaks up the custard-like coating before frying.
Baker's bread
Absorbs the egg and milk mixture and crisps to form the toast base.
Melted butter
Fat that fries the soaked bread, adding richness and golden browning.
White sugar
Sweetens the lemon sauce and helps stabilise the whipped egg whites.
Lemon juice
Adds acidity and bright flavour to the sauce.

The step that matters

Heat the lemon sauce gently after adding the juice. Egg-based sauces thicken as the proteins set with heat, but too much heat can curdle or scramble the eggs. Gentle heating keeps the sauce smooth.

Swap the lemon

How well each one fits the dish's main ingredients (egg, milk, bread, butter, sugar):

  1. Vanillafits better
  2. Figfits better
  3. Peachfits about as well

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.
