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
- Cream of tartar
- Creates acidity that reacts with baking soda to help the doughnuts rise and stay tender.
- Baking soda
- Reacts with the acid in cream of tartar to produce gas, lifting the dough as it fries.
- Butter
- Adds fat for tenderness and richness in the dough.
- Sweet milk
- Provides moisture that hydrates the flour and binds the dough.
- Sugar
- Adds sweetness and helps the doughnuts brown in the hot lard.
The step that matters
Frying the dough in hot lard. If the lard is not hot enough, the dough absorbs excess fat and becomes greasy and heavy. If it is too hot, the outside browns before the centre cooks. Steady, moderate heat gives a light, evenly cooked doughnut.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, milk, cream):
- Cinnamonfits about as well
- Nutmegthe original
- Gingerfits less well
- Macefits less well
Fit is the average pairing score against sugar, butter, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
