Why it works: Potato and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,052 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Doughnuts
Ingredients
Directions
Prepare the potato batter
Boil the potatoes until tender.
Mash the boiled potatoes finely.
Add water, yeast cakes, and enough flour to create a batter.
Heat the milk until lukewarm.
Melt the lard in the heated milk.
Stir in enough flour to make a very thick batter.
Add the mashed potato mixture to the batter.
Let the batter rise overnight.
Shape the dough
In the morning, mix in sugar, beaten eggs, nutmeg, and salt.
Knead in enough flour to roll out the dough.
Let the dough rise again until spongy and light.
Roll out the dough to ½ inch thick.
Cut the rolled dough into shapes.
Let the cut dough rise again until very light.
Fry
Fry the doughnuts in 2 pounds of lard until golden brown.

Flour and milk 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
- Potatoes
- Add moisture and starch that keep the dough soft and tender.
- Yeast cakes
- Produce gas during rising, making the dough light and spongy.
- Eggs
- Add structure and richness, helping the dough hold its shape.
- Lard
- Adds fat for tenderness and gives the doughnuts their frying richness.
- Milk
- Adds moisture and richness and helps feed the yeast.
- Sugar
- Adds sweetness and helps the doughnuts brown when fried.
The step that matters
Let the dough rise fully before frying. Yeast needs time to produce gas; under-proofed dough fries up dense and heavy. Rising in two stages builds the light, spongy texture, so each rise should reach the stated stage before shaping or frying.
Swap the potato
How well each one fits the dish's main ingredients (flour, milk, sugar, egg, nutmeg):
- Arrowrootfits better
- Sweet potatofits better
- Parsnipfits better
- Potatothe original
Fit is the average pairing score against flour, milk, sugar, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
