Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set during frying to give the bread a firm, custardy structure.
- Milk
- Adds moisture and softens the bread while keeping the interior tender.
- Bread
- Absorbs the egg mixture and fries to a golden, crisp-edged crust.
- Butter
- Conducts heat in the pan and promotes browning and rich flavour.
The step that matters
Fry the bread until golden brown. Frying over moderate heat lets the egg set inside the bread before the outside burns. Browning from the Maillard reaction adds flavour and colour, so cooking too hot scorches the crust while leaving the centre wet.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
