Why it works: Butter and bread 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the milk to the bread and helps the soaked slices set when fried.
- Milk
- Soaks into the bread, adding moisture and a soft, custardy interior.
- Bread
- Absorbs the egg and milk mixture, then browns and crisps in the hot fat.
- Butter
- Adds richness and flavour and helps the bread brown in the pan.
- Sugar
- Adds sweetness and helps the exterior caramelise when browned.
The step that matters
Fry the soaked bread in the hot fat until brown on both sides. If the fat is not hot enough, the soaked bread absorbs fat and turns greasy instead of browning. Browning comes from the Maillard reaction, which needs sufficient heat on the surface of the bread.
Swap the cinnamon
How well each one fits the dish's main ingredients (milk, egg, sugar, butter, bread):
- Cinnamonthe original
- Nutmegfits about as well
- Parsleyfits less well
- Capersfits less well
Fit is the average pairing score against milk, egg, sugar, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
