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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Sour milk
- Its acidity reacts with baking soda to produce gas that lifts the dough.
- Baking soda
- Reacts with the acid in sour milk and sugar to release carbon dioxide, helping the doughnuts rise.
- Light brown sugar
- Adds sweetness, moisture, and browning during frying.
- Flour
- Provides structure, forming the dough that holds the doughnut shape.
- Lard
- Adds fat, giving the doughnuts a tender texture.
The step that matters
Mixing in the flour. Adding too much flour makes the dough tough and dense, because gluten develops and the dough loses the softness that lets it rise. Stop once the dough just comes together.
