Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Raised Doughnuts II
Ingredients
Directions
Make the dough
In a bowl, beat the eggs and mix in the sugar and butter.
Add the potato yeast, baking soda, and salt, then stir in enough flour to make a stiff dough.
Cover the bowl and let the dough rise overnight.
Shape and fry
In the morning, roll out the dough and cut it into doughnut shapes.
Let the cut doughnuts rise again until very light.
Fry the doughnuts until golden brown.

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
- Add richness and help bind the dough into a structure that holds its shape.
- Potato yeast
- Produces gas as it ferments, making the dough rise and become light.
- Butter
- Adds fat, which softens the crumb and gives a tender texture.
- Sugar
- Feeds the yeast and adds sweetness and some browning during frying.
- Baking soda
- Reacts with acidity in the dough to release gas, adding lift.
- Flour
- Forms the gluten network that gives the dough its structure and stiffness.
The step that matters
Let the cut doughnuts rise again until very light. Under-proofed doughnuts stay dense and may burst or stay doughy inside when fried, while over-proofed ones can collapse or absorb excess oil. The dough should look airy before it goes into the fat.
Swap the potato
How well each one fits the dish's main ingredients (egg, sugar, butter, flour):
- Chivefits better
- Leekfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against egg, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
