Why it works: Flour and pepper are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 50,459 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

What each ingredient does
- Flour
- Thickens the liquid as its starch swells and gelatinizes when heated, giving the sauce body.
The step that matters
Cook over medium heat, stirring constantly. Flour starch thickens only as the liquid heats, but the sauce can scorch on the bottom of the pan if left unstirred. Constant stirring spreads heat evenly, keeps lumps from forming, and prevents burnt flavor.
