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 ↓
Plain Doughnuts
Ingredients
Directions
Make the dough
In a large bowl, mix the flour, sugar, baking powder, salt, and butter until well combined.
Add the beaten eggs and enough sweet milk to form a soft dough.
Flavor the dough with nutmeg or cinnamon.
Fry
Drop spoonfuls of the dough into boiling lard and fry until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure of the dough.
- Eggs
- Bind the dough and add richness and structure.
- Butter
- Adds fat, giving the doughnuts a tender texture.
- Baking powder
- Releases gas that lifts the dough for a lighter crumb.
- Sugar
- Adds sweetness and helps the exterior brown during frying.
The step that matters
Frying the dough spoonfuls in boiling lard. The lard must be hot enough that the dough sets and browns quickly on the outside. If the fat is too cool, the doughnuts absorb excess oil and turn greasy and heavy before they cook through.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, milk):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against flour, sugar, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
