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
- Oysters
- Main flavour; their briny, savoury taste forms the base of the sauce.
- Butter
- Adds fat and richness, giving the sauce a smooth, creamy mouthfeel.
- Flour
- Thickens the liquid as its starch swells and gelatinises when heated.
The step that matters
Adding the flour and bringing to a boil. Flour thickens only when its starch is heated to a boil and swells. Stirring it in well before boiling prevents lumps and gives an even, smooth sauce.
