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 ↓

Flour and butter 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
- Flour
- Forms the dough's structure, which traps gas and sets when fried.
- German yeast
- Produces gas during the rise, making the doughnuts light and airy.
- Egg
- Adds richness and helps bind the dough for a tender crumb.
- Butter
- Adds fat for a softer, more tender texture.
- Tepid milk
- Provides the liquid that hydrates the flour and activates the yeast.
- Castor sugar
- Feeds the yeast and adds sweetness and browning to the surface.
The step that matters
Let the dough rise fully before shaping. Yeast gas expands the dough during the rise; if it is under-proofed the doughnuts stay dense and may be heavy after frying.
