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.
