Why it works: Mace and nutmeg match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 6,557 recipes mention both. Both carry myristicin, which smells spice, warm. The science ↓

The recipe

Ingredients

Contains: milk, wheat, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare and bake

  1. Preheat the oven to 400°F (200°C).

  2. Grease a dish with butter and place the cleaned cod's head in it.

  3. Add sweet herbs, onion with cloves, mace, pepper, bruised nutmeg, lemon peel, horseradish, and water.

  4. Dust the head with flour, sprinkle grated nutmeg, dot with butter, and cover with breadcrumbs.

  5. Bake in the oven until done, then transfer to a serving dish.

Make the sauce

  1. Pour the cooking liquid into a saucepan and boil for 3-4 minutes.

  2. Strain the liquid and add red wine, ketchup, shrimp, oysters, mushroom pickle, and butter rolled in flour.

  3. Stir and boil until thick, then strain and pour over the cod's head.

Garnish and serve

  1. Garnish with fried toast, crisped parsley, lemon wedges, and scraped horseradish.

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

What each ingredient does

Cod's head
Forms the main body of the dish and provides the flesh and flavour base for the stew.
Butter
Adds richness and helps the breadcrumb topping brown during baking.
Flour
Thickens the sauce and helps the breadcrumb crust hold together.
Red wine
Adds acidity and depth to the sauce as it reduces.
Shrimp
Contributes savoury seafood flavour and body to the sauce.
Oysters
Contributes briny seafood flavour and a soft, rich texture to the sauce.

The step that matters

Boiling the sauce until thick. Flour-butter paste thickens only when it is boiled, which gelatinises the starch. Stirring keeps it smooth and stops lumps forming. Undercooked sauce stays thin and floury-tasting, while overcooking can make it stiff.

Flavor stand-ins for the onion

How well each one fits the dish's main ingredients (butter, clove, mace, white pepper, nutmeg, lemon, horseradish):

  1. Carrotbetter flavor fit
  2. Potatobetter flavor fit
  3. Capsicumbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against butter, clove, mace, white pepper, nutmeg, lemon, horseradish. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
