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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Oysters
- Provide the main flavour and the sauce's base, releasing their liquor as they heat.
- Butter
- Adds richness and fat, giving the sauce a smooth, rounded mouthfeel.
- Flour
- Thickens the sauce as it boils, giving it body and a spoonable texture.
The step that matters
Boiling the sauce after adding the butter and flour. Flour only thickens fully when the mixture reaches a boil and stays there briefly; the starch granules swell and set the sauce. Undercooked flour leaves a pasty, raw taste.
