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 ↓

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 structure that holds the dough together and lets the doughnuts keep their shape.
- Eggs
- Add richness and structure, and the whipped whites lighten the dough.
- Sour milk
- Reacts with the baking soda and adds moisture and tang to the dough.
- Baking soda
- Reacts with the acidic sour milk to produce gas that leavens the doughnuts.
- Sugar
- Adds sweetness and helps the doughnuts brown during frying.
- Butter
- Adds fat for tenderness and flavor in the dough.
The step that matters
Heat the lard gently. Lard that is too hot will brown the outside of the doughnuts before the centre cooks through. Keeping the fat moderately hot lets the dough cook evenly and turn golden without burning.
Swap the mace
How well each one fits the dish's main ingredients (flour, sugar, cinnamon, butter, egg, milk):
- Nutmegfits better
- Cardamomfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against flour, sugar, cinnamon, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
