Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Codfish
Forms the main body of the dish, cooked gently in the poaching water.
Oysters
Provide the savory, briny flavor that defines the sauce.
Butter
Adds richness and fat, giving the sauce a smooth, rounded mouthfeel.
Milk
Forms the creamy base of the sauce, adding body and mild sweetness.
Flour
Thickens the milk so the sauce becomes smooth and lightly bodied.

The step that matters

Whisk in milk mixed with flour. Adding flour to hot liquid without first mixing it with milk can form lumps. Blending flour into the milk first, then whisking, keeps the sauce smooth as it thickens.

Swap the mace

How well each one fits the dish's main ingredients (flour, clove, lemon, oyster, fish, pepper, butter):

  1. Parsleyfits better
  2. Nutmegfits better
  3. Marjoramfits better
  4. Macethe original

Fit is the average pairing score against flour, clove, lemon, oyster, fish, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
