Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking powder
- Releases gas in the dough so the doughnuts rise and turn light.
- Eggs
- Bind the dough and add richness and structure.
- Sugar
- Sweetens the dough and helps the surface brown when fried.
- Butter
- Adds fat that makes the dough tender and rich.
- Milk
- Adds moisture that hydrates the flour and forms the dough.
- Lard
- Fat for frying that carries heat and gives a crisp golden crust.
The step that matters
Fry in boiling lard until golden brown. The fat must be hot enough to set the outside quickly. If it is too cool, the dough soaks up grease and turns heavy and oily. If it is too hot, the outside browns before the centre cooks through.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, milk, egg):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Parsleyfits less well
Fit is the average pairing score against sugar, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
