Why it works: Flour and milk 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 ↓

What each ingredient does
- Flour
- Thickens the milk as its starch swells when heated, giving the mixture body.
- Milk
- Forms the liquid base that the flour thickens into a smooth, pourable sauce.
The step that matters
Stirring while returning to a boil. Flour mixed into liquid can clump when heated, forming lumps. Constant stirring disperses the starch granules so they hydrate evenly and the mixture thickens smoothly.
