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 form the body of the oyster sauce.
- Butter
- Adds richness and a smooth, glossy mouthfeel to the sauce.
- All-purpose flour
- Thickens the oyster liquor and butter into a sauce that clings to the steak.
The step that matters
Boiling the sauce after adding the butter and flour. Flour only thickens once its starch granules swell in boiling liquid. Letting the sauce boil for the full minute ensures it thickens fully and loses any raw floury taste.
“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.
