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 texture of the sauce, cooked until plump.
- Butter
- Adds fat and richness to the sauce base.
- Flour
- Thickens the sauce with the butter as a roux.
- Milk
- Forms the liquid body of the sauce, giving it creaminess.
- Oyster liquor
- Adds the briny oyster flavour to the sauce liquid.
The step that matters
Cooking the oysters until plump. Oysters cook quickly, and overcooking makes them tough and shrunken. Stop once they plump and their edges curl, then return them to the sauce off the heat.
