Why it works: Milk and butter 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
Ingredients
Directions
Make the dough
Beat the eggs and sugar together.
Dissolve the baking soda in the milk, add the melted butter, and mix with the egg and sugar mixture.
Sift the flour and cream of tartar together twice, then beat well and add the nutmeg.
Ensure the dough is not too stiff; adjust flour as needed.
Shape and fry
Roll out the dough, cut with a doughnut cutter, and fry in hot lard.

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
- Eggs
- Bind the dough and add richness and structure.
- Flour
- Provides the structure that holds the dough together when fried.
- Cream of tartar
- Acidifies the dough so it reacts with baking soda to help it rise.
- Baking soda
- Reacts with the acid in cream of tartar to produce gas that lightens the dough.
- Sugar
- Adds sweetness and helps the doughnut brown during frying.
The step that matters
Keep the dough soft, not stiff. Too much flour makes the dough stiff and dense, so the doughnuts fry up tough. Adjust flour gradually so the dough stays soft enough to roll and cut cleanly.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, egg, sugar, milk, butter, cream):
- Nutmegthe original
- Cinnamonfits about as well
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against flour, egg, sugar, milk, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
