Why it works: Nutmeg and flour 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 ↓
Delicious Doughnuts
Ingredients
Directions
Make the dough
In a bowl, combine sour buttermilk, eggs, granulated sugar, lard, salt, and nutmeg.
Gradually add flour until a soft dough forms.
Fry and finish
Fry the dough in hot oil until golden brown.
Remove from oil and roll in powdered sugar.

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.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Sour buttermilk
- Adds acidity and moisture, giving the dough a tender crumb.
- Eggs
- Bind the dough and add structure and richness.
- Granulated sugar
- Adds sweetness and helps the doughnuts brown in the fryer.
- Lard
- Adds fat, giving a tender texture and rich flavor.
- Flour
- Provides the structure that holds the soft dough together.
The step that matters
Fry until golden brown. Frying in hot oil cooks the centre as the outside browns. If the oil is too cool, doughnuts absorb excess oil and turn greasy; if too hot, they brown before the inside is cooked.
Swap the nutmeg
How well each one fits the dish's main ingredients (buttermilk, egg, sugar, flour):
- Jalapenofits better
- Cinnamonfits about as well
- Nutmegthe original
- Dillfits less well
Fit is the average pairing score against buttermilk, egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
