Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main ingredient and their briny liquor, which gives the dish its flavor.
- Cream or milk
- Adds richness and moisture, giving the oysters a creamy body.
- Butter
- Adds fat and richness to the creamy mixture.
- Flour
- Thickens the liquid as it boils, giving the sauce body.
The step that matters
Let the mixture boil again. Flour mixed with butter needs to boil to fully thicken the cream. Boiling activates the starch, so the sauce turns smooth instead of pasty or raw-tasting. Overcooking oysters, however, toughens them, so the boil should be brief.
