Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the base of the sauce and carries flavour, giving it richness.
- Flour
- Thickens the butter and oyster liquor into a light sauce.
- Oyster liquor
- Provides the liquid and briny oyster flavour for the sauce.
- Oysters
- Are the main ingredient, cooked briefly until their edges curl.
The step that matters
Cooking the oysters until the edges curl. Oysters turn firm and rubbery when overcooked. A short cook in the hot sauce is enough to warm them through while keeping them tender.
