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 tender texture of the sauce.
- Butter
- Forms the fat base of the roux, adding richness and a smooth body.
- Flour
- Thickens the sauce by forming a roux with the butter.
- Oyster liquor
- Adds salty, briny flavour and liquid to the sauce.
- Milk
- Adds moisture and creaminess, mellowing the sauce.
The step that matters
Gradually stir in the liquor and milk. Adding the liquid slowly while stirring lets the starch in the roux disperse evenly and swell, which prevents lumps and gives a smooth, properly thickened sauce.
