Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Dry, absorbent bread soaks up the egg mixture and holds its shape while frying.
- Egg
- Sets when cooked, binding the soaked bread into a custardy interior with a firm exterior.
- Milk
- Adds moisture and loosens the egg so it coats the bread evenly.
- Butter
- Adds fat for browning the surface and a rich flavour.
- Sugar
- Adds sweetness and helps the surface brown when it is sprinkled on with cinnamon.
The step that matters
Dip the bread quickly into the egg mixture. Bread that soaks too long turns soggy and falls apart in the pan, while a brief dip lets the surface absorb just enough custard to cook through and brown well.
“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.
