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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread dough
- Provides the base structure that traps gas and rises to a light texture.
- Light brown sugar
- Sweetens the dough, adds moisture, and helps the surface brown when fried.
- Butter
- Adds fat that tenderises the crumb and enriches the flavour.
- Egg
- Enriches the dough and adds structure and lightness when beaten.
The step that matters
Fry in hot lard until golden brown. If the lard is too cool, the doughnuts absorb excess fat and turn greasy. If it is too hot, the outside browns before the centre cooks through. Steady, moderately hot fat gives an even golden crust and a fully cooked interior.
Swap the nutmeg
How well each one fits the dish's main ingredients (bread, sugar, butter, egg):
- Cinnamonfits about as well
- Nutmegthe original
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against bread, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
