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 ↓
Doughnuts “never Fail”
Ingredients
Directions
Make the dough
Cream the sugar with the butter.
Add the egg yolks and beat for three to four minutes.
Stir in the sweet milk, salt, and grated nutmeg.
Mix in enough flour to handle along with the baking powder.
Fry and drain
Cut out the doughnuts before frying in deep fat.
Once fried, place them on paper to cool and absorb excess fat.

Butter and flour 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
- Sugar
- Adds sweetness and helps the dough brown lightly when fried.
- Butter
- Adds fat for tenderness and a richer flavor in the dough.
- Egg yolks
- Add richness and help bind the dough.
- Sweet milk
- Provides moisture that hydrates the flour and builds the dough.
- Flour
- Forms the structure of the dough so it can be handled and cut.
- Baking powder
- Releases gas that makes the doughnuts rise and lighten when fried.
The step that matters
Frying in deep fat. The fat must be hot enough to set the outside quickly. If it is too cool, doughnuts absorb excess oil and turn greasy; if too hot, the outside browns before the inside cooks through.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, flour):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against sugar, butter, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
