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
- Starch that swells in hot milk and thickens it into a smooth sauce.
- Milk
- Forms the liquid base that the flour thickens into a creamy mixture.
The step that matters
Stirring while the mixture boils. Flour starch settles and scorches on the pan bottom if left still, and it clumps if not dispersed. Constant stirring keeps the starch evenly suspended so it thickens smoothly.
