Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- The main ingredient, providing the body and briny flavor of the dish.
- Butter
- Adds fat for richness and a smooth, buttery flavor to the sauce.
- Flour
- Thickens the liquid into a sauce as its starch swells when heated.
- Egg yolk
- Enriches and further thickens the sauce, adding richness and smoothness.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances its flavor.
- Mustard
- Adds a sharp, savory bite that cuts through the richness of the sauce.
The step that matters
Gradually pour in the oyster liquid while stirring constantly. Flour clumps if liquid is added all at once. Adding the liquid slowly while stirring lets the starch disperse evenly before the mixture thickens, giving a smooth sauce.
Swap the mustard
