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. Rub a baking dish with butter and place the cleaned cod's head inside.

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

  4. Dust the cod's head with flour, sprinkle with grated nutmeg, and dot with pieces of butter.

  5. Sprinkle breadcrumbs over the top and bake in the oven.

Make the sauce

  1. Once cooked, transfer the cod's head to a serving dish and keep warm over boiling water.

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

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

  4. Stir well and boil until thickened, then strain again and pour over the cod's head.

Garnish and serve

  1. Garnish with toasted bread, crispy 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, providing the flaky fish that is served.
Butter
Adds richness and moisture, and helps the breadcrumb topping brown in the oven.
Breadcrumbs
Form a crisp, browned crust on top while the fish cooks.
Red wine
Adds acidity and depth of flavour to the thickened sauce.
Flour
Thickens the sauce when rolled with butter and stirred in.
Shrimp
Contributes savoury seafood flavour and body to the sauce.

The step that matters

Thickening the sauce. Flour-rolled butter must be stirred in and boiled until thickened so the starch cooks fully; otherwise the sauce stays thin and tastes raw-floury.

Flavor stand-ins for the onion

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

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

Fit is the average pairing score against butter, clove, mace, pepper, white pepper, nutmeg, lemon. 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).
