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

What each ingredient does

Bread
Forms the base that soaks up the milk and egg and then crisps when fried.
Eggs
Egg yolks enrich the soaking milk, while beaten whites add a light, frothy topping.
Milk
Moistens the bread so the slices soften before frying.
Sugar
Sweetens the frothy topping and balances the sharpness of the lemon.
Lemon juice
Adds acidity and bright flavour that cuts through the sweetness.
