Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Browned with butter, it thickens the liquid into a gravy-like sauce.
- Butter
- Browned with the flour to add nutty flavour and richness to the sauce.
- Oysters
- Provide the main seafood flavour and savoury body of the sauce.
The step that matters
Brown the butter and flour together. Cooking the flour in butter lets its starch toast and thicken properly, while the butter browns for flavour. Stopping too early leaves a raw, pasty taste, and burning gives bitterness.
“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.
