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
Ingredients
Directions
Make the dough
In a bowl, beat the eggs and mix in the sugar and melted butter.
Add the sweet milk with dissolved baking soda.
In a separate bowl, combine flour with cream of tartar and spices.
Gradually mix the dry ingredients into the wet ingredients until a dough forms.
Handle the dough as little as possible on a floured surface.
Fry
Shape and fry the doughnuts 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.

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
- Eggs
- Bind the dough and add richness and structure as they set when fried.
- Baking soda
- Reacts with the cream of tartar to produce gas that lifts the dough.
- Cream of tartar
- Acidifies the dough so it reacts with the baking soda to help it rise.
- Flour
- Forms the dough's structure once mixed with the wet ingredients.
- Sugar
- Adds sweetness and contributes to browning in the fried surface.
The step that matters
Handle the dough as little as possible. Mixing or kneading develops gluten in the flour, making the doughnuts tough. Minimal handling keeps them tender, and the leavening gas is more effective when the dough is not overworked.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, cream, flour):
- Nutmegthe original
- Cinnamonfits about as well
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against egg, sugar, butter, milk, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
