Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Browned to give the sauce a nutty flavour and forms the base of the roux.
- Flour
- Cooked with the butter to form a roux that thickens the sauce.
- Oyster liquor
- Adds the briny oyster flavour and liquid that becomes the body of the sauce.
- Brown stock
- Supplies savoury depth and liquid, helping the sauce thicken and taste rich.
- Oysters
- Provide the main seafood flavour and texture; gentle heat keeps them tender.
The step that matters
Browning the butter and flour. Browning the butter and then the flour develops nutty, toasted flavour and colour in the roux. Stopping too early leaves a pale, raw-tasting sauce, while going too far gives a bitter burnt taste.
