Why it works: Mace and nutmeg are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 6,557 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Croute Aux Crevettes, or Shrimp-toast
Ingredients
Directions
Prepare the shrimp liquid
Boil the shrimp heads in 1½ pints of water for 30 minutes, then strain the liquid through a fine sieve.
Make the sauce
In a saucepan, melt 2 ounces of butter over medium heat. Stir in 1 teaspoon of flour, ¼ teaspoon of ground mace, cayenne pepper, and grated nutmeg until the flour begins to brown.
Gradually add the strained shrimp liquid to the saucepan and bring to a boil.
Add the shelled shrimp and heat until they are hot throughout.
Fry the toast and serve
Fry the hollowed toast in fresh butter until light brown.
Pour the shrimp mixture over the toast and serve. Optionally, add veal broth, essence of anchovies, sherry, lemon juice, or beaten egg yolks for extra flavor.

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 meat that is served over the toast.
- Butter
- Carries the spices and fries the toast, adding richness and browning.
- Flour
- Cooked in the butter until it browns, it thickens the shrimp liquid into a sauce.
- Bottom crust of a loaf
- Forms the base that soaks up the sauce, holding its shape when fried in butter.
The step that matters
Browning the flour in the butter. Cooking the flour in butter until it just begins to brown removes its raw taste and thickens the sauce. Stopping too early leaves a pasty flavor, and cooking too long can scorch it and make the sauce bitter.
Swap the mace
How well each one fits the dish's main ingredients (shrimp, butter, flour, pepper, nutmeg, veal, sherry):
- Parsleyfits better
- Cinnamonfits better
- Thymefits better
- 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.
