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

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

  3. Dust the head with flour, sprinkle with grated nutmeg, add bits of butter, and cover with breadcrumbs.

  4. Bake in a 400°F (200°C) oven until done.

Make the sauce

  1. Remove the head from the dish and place it in a serving dish over boiling water to keep warm.

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

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

  4. Stir well and boil until thick, then drain 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 and gives the flavour base of the bake.
Breadcrumbs
Form a crisp, browned topping over the fish during baking.
Butter rolled in flour
Thickens the sauce so it clings to the fish when boiled.
Red wine
Adds acidity and depth to the sauce.
Oysters
Add briny flavour and tender texture to the sauce.
Shrimp
Add savoury seafood flavour and body to the sauce.

The step that matters

Boil the sauce until thick. Boiling reduces the liquid and lets the flour-thickened butter set the sauce. Undercooked flour leaves a raw, pasty taste, and an unthickened sauce runs off the fish instead of coating it.

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).
