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 ↓
Old Fashioned Doughnuts
Ingredients
Directions
Make the dough
Cream the butter and sugar together.
Add the grated nutmeg, salt, beaten eggs, and milk.
Sift the flour with the baking powder and add it to the mixture.
Dredge a board with flour, roll out the dough, and cut it into strips or rings.
Fry and finish
Fry the doughnuts in hot oil until golden brown. Ensure they are cooked all the way through.
Drain on coarse paper to absorb excess grease. For less grease, briefly plunge each doughnut in hot water after frying.
Roll in powdered sugar when cool, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough that holds the doughnut shape while frying.
- Eggs
- Add richness and help bind the dough so it holds together.
- Baking powder
- Releases gas that makes the doughnuts rise and turn light.
- Butter
- Adds fat that tenderises the crumb and gives richer flavour.
- Sugar
- Adds sweetness and helps browning during frying.
- Milk
- Provides moisture that hydrates the flour into a workable dough.
The step that matters
Frying until cooked through. The outside browns quickly while the centre can stay raw. Frying at a steady hot temperature until golden and fully cooked through prevents a doughy middle and greasy, heavy results.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, egg, flour, milk):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against sugar, butter, egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
