Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts into the liquid to give the sauce its rich fat and smooth body.
- Flour
- Thickens the butter and water or stock into a smooth, lightly bodied sauce.
- Water or stock
- Forms the liquid base that the butter and flour are emulsified and thinned into.
The step that matters
Remove from heat as soon as it comes to a boil. Flour-thickened liquids reach full thickness when they boil, and continued heating can make the sauce thick, gluey or separated. Stopping promptly keeps it smooth.
“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.
