Why it works: Butter and milk 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 ↓
American Doughnuts
Ingredients
Directions
Prepare the dough
Mix the yeast with a little sugar and lukewarm water.
Rub the butter into the flour, add sugar and a pinch of salt.
Pour the yeast mixture into the center, adding a little of the milk.
Let it stand for 15 minutes, then mix to a light dough with the egg and the rest of the milk.
Let it rise for at least 1 hour.
Shape and fry
Roll out the dough quickly, then cut out and line well-floured patty tins.
Place a little jam in the center of each, cover with a lid of dough, wetting the edges.
Allow to rise again for half an hour.
Slip out into hot fat and fry for about 6 to 7 minutes.
Roll in castor sugar and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough that traps gas and holds the doughnut's shape.
- Yeast
- Produces gas during fermentation, making the dough rise and become light.
- Butter
- Adds fat that tenderises the crumb and gives a richer texture.
- Egg
- Adds structure and richness, helping bind the dough and add softness.
- Milk
- Provides moisture that hydrates the flour and helps form a soft dough.
- Sugar
- Feeds the yeast and adds sweetness and browning during frying.
The step that matters
Frying the shaped doughnuts. The fat must be hot enough to seal and cook the outside quickly; if it is too cool, doughnuts absorb excess oil and turn greasy and heavy.
