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 ↓
Doughnuts No. 1
Ingredients
Directions
Make the dough
Beat the white sugar and eggs together in a bowl.
Add buttermilk, melted butter and lard, baking soda, and baking powder.
Sift in enough flour to make a soft dough.
Turn the dough out onto a floured surface and roll it out using just enough flour to prevent sticking.
Fry and finish
Heat a kettle filled halfway with fat until boiling hot.
Cut the dough into desired shapes and drop them into the hot fat.
Fry until golden brown, turning 2 or 3 times for even cooking.
Remove the doughnuts and place them on soft paper to absorb excess grease.
Dust with powdered sugar while hot.
Once completely cool, store in a stone jar.

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 it sets in the fat.
- Buttermilk
- Adds moisture and acidity that react with the baking soda for tenderness and rise.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that lightens the dough.
- Baking powder
- Provides additional lift so the doughnuts puff while frying.
- White sugar
- Adds sweetness and helps browning on the fried surface.
- Butter and lard
- Add fat that contributes tenderness and flavor to the dough.
The step that matters
Frying at the right heat. The fat must be boiling hot before the dough goes in. If it is too cool, doughnuts absorb excess oil and turn greasy and heavy instead of browning quickly and cooking through.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, buttermilk, egg, butter, flour):
- Cinnamonfits about as well
- Nutmegthe original
- Jalapenofits about as well
- Capersfits less well
Fit is the average pairing score against sugar, buttermilk, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
