Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the creamy base of the sauce and gives it body.
- Butter
- Adds fat and richness, giving the sauce a smooth, rounded flavour.
- Rice or wheat flour
- Thickens the liquid as its starch swells when heated, giving the sauce body.
- Oysters
- Provide the main seafood flavour and tender texture in the sauce.
- Lemon juice
- Adds acidity that brightens the rich, creamy sauce.
The step that matters
Stir the wet flour into the sauce. Flour must be wetted with cold water first so it disperses without lumps. Its starch then thickens evenly as the sauce heats, and stirring keeps it from clumping on the bottom of the pan.
Swap the parsley
How well each one fits the dish's main ingredients (milk, butter, rice, pepper, lemon, oyster):
- Parsleythe original
- Thymefits about as well
- Cinnamonfits less well
- Marjoramfits less well
Fit is the average pairing score against milk, butter, rice, pepper, lemon, oyster. Candidates are from the same food group and used in at least 100 recipes.
