Directions

Prepare the stock

  2. Stir in 1 teaspoon of flour, ¼ teaspoon of ground mace, cayenne pepper, and grated nutmeg.

  3. Cook the mixture, stirring often, until the flour begins to brown.

  4. Gradually add the strained shrimp liquid and bring to a boil.

  5. Add the shelled shrimp and heat until hot throughout.

Fry the toast and serve

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

What each ingredient does

Shrimp
Provides the main flavour and the body of the dish once heated through.
Butter
Carries the spices and enriches the sauce while it is fried and browned on the toast.
Flour
Thickens the sauce as it cooks and browns in the melted butter.
Bread
Forms the base that soaks up the sauce and fries to a light brown crust.

The step that matters

Cook the flour until it just begins to brown. Flour cooked in fat must be stirred often; too little cooking leaves a raw starchy taste, while overcooking scorches it and gives a bitter flavour. Stirring also keeps lumps from forming before the liquid is added.

Swap the mace

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

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

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