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

What each ingredient does

Shrimp
Provides the main flavor and the substance of the dish once heated through in the sauce.
Butter
Carries flavor and enriches the sauce, and browns the toast when fried.
Flour
Thickens the melted butter into a roux that gives the sauce body.
Ground mace
Adds a warm, aromatic spice flavor to the sauce.
Bread toast
Forms a crisp, golden base that holds the shrimp mixture.

The step that matters

Browning the flour in the butter. Flour must be cooked until it just begins to brown so it thickens well and loses its raw, pasty taste. Stopping too early leaves the sauce floury, while cooking too long can scorch it and turn it bitter.

Swap the mace

How well each one fits the dish's main ingredients (shrimp, butter, flour, pepper, nutmeg, veal, sherry):

  1. Parsleyfits better
  2. Cinnamonfits better
  3. Thymefits better
  4. Macethe original

Fit is the average pairing score against shrimp, butter, flour, pepper, nutmeg, veal, sherry. Candidates are from the same food group and used in at least 100 recipes.
