Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and helps the surface brown golden in the hot oil.
- Sweet milk
- Provides the liquid that hydrates the flour and keeps the dough moist.
- Egg
- Binds the mixture and adds structure and richness to the dough.
- Baking powder
- Releases gas as the dough heats, helping the doughnuts rise and become light.
- Flour
- Forms the gluten and starch network that gives the dough its body and shape.
The step that matters
Fry in hot oil until golden brown. If the oil is not hot enough, the dough absorbs oil and turns greasy and heavy. If it is too hot, the outside browns before the centre cooks through. Steady heat gives an even, golden, lightly crisp exterior.
