Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
American Doughnuts
Ingredients
Directions
Prepare the dough
Beat the eggs well.
Add the sugar, grated nutmegs, salt, baking soda, and cream of tartar, and mix.
Add the milk and beat all together.
Gradually mix in enough flour to make a soft dough.
Roll into balls the size of a small egg.
Fry and serve
Heat a pot of lard until boiling (with blue smoke).
Drop in the balls and fry for 8 to 10 minutes until golden brown.
Lift them out with a wire spoon or skimmer.
Roll them in sifted sugar while hot and serve either hot or cold.

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.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 in the frying fat.
- Baking soda
- Reacts with cream of tartar to produce gas that lifts the dough and gives a light texture.
- Cream of tartar
- Acidifies the dough so it reacts with baking soda, helping the doughnuts rise.
- Castor sugar
- Sweetens the dough and helps the surface brown during frying.
- New milk
- Adds moisture so the flour forms a soft, tender dough.
- Flour
- Forms the main structure that holds the doughnut shape while frying.
The step that matters
Heat the lard until boiling before frying. If the fat is not hot enough, the doughnuts absorb excess oil and turn greasy and heavy instead of crisp and golden. Too hot, and the outside browns before the centre cooks.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, sugar, cream, egg, flour):
- Nutmegthe original
- Cinnamonfits about as well
- Jalapenofits less well
- Turmericfits less well
Fit is the average pairing score against milk, sugar, cream, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
