Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Directions
Make the batter
Whisk the eggs, milk, and flour together to make a thin batter.

Serve warm with syrup or molasses.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and help set the coating around the bread as it cooks.
- All-purpose flour
- Thickens the milk and eggs into a batter that clings to the bread.
- Milk
- Loosens the batter and adds moisture so the bread stays soft inside.
- Stale bread
- Dry bread soaks up the batter without falling apart, giving a custard-like center.
- Melted butter
- Conducts heat in the pan and promotes browning and rich flavor on the surface.
The step that matters
Fry the coated bread slices until browned on both sides. Medium heat lets the batter set and brown evenly before the outside burns. Too high a heat scorches the surface while the egg in the center stays runny.
“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.
