Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Risen Doughnuts
Ingredients
Directions
Make the sponge
Scald the milk and let it cool to lukewarm.
Add melted butter, beaten eggs, sugar, yeast, and enough flour to make a sponge.
Beat well and let it stand in a warm place for about three hours.
Make the sponge in the evening or late afternoon for overnight kneading.
Make the dough
When the sponge is light, add enough flour to make a soft dough.
Knead lightly, cover, and let it rise in a warm place overnight.
Shape and fry
In the morning, roll out the dough carefully without kneading.
Place the dough on a floured cloth and let it stand for one hour.
Fry in smoking hot oil, dropping the doughnuts with the air-exposed side down.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Ferments the sponge so the dough rises and becomes light.
- Eggs
- Add structure and richness to the dough and help it hold its shape.
- Butter
- Adds fat for tenderness and richness in the dough.
- Milk
- Provides liquid that hydrates the flour and feeds the yeast.
- Sugar
- Feeds the yeast and adds sweetness and browning in frying.
- Flour
- Forms the gluten network that gives the dough its body.
The step that matters
Rolling out the dough without kneading. Kneading after the overnight rise would knock out the gas and gluten structure the yeast built, so the dough must be handled gently and rolled, not worked.
