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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Produces gas that makes the dough rise and become light and airy.
- Flour
- Forms the gluten structure that traps gas and gives the doughnuts their body.
- Egg
- Adds structure and richness, helping the dough hold its shape and texture.
- Butter
- Adds fat for tenderness and a richer crumb.
- Sugar
- Feeds the yeast and adds sweetness and browning during frying.
- Milk
- Provides moisture and liquid that hydrates the flour and dissolves the sugar.
The step that matters
Let the squares rise until very light. Under-proofed doughnuts stay dense and heavy, while over-proofed ones may collapse or absorb excess oil. The dough should be visibly puffed and airy before frying.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
