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 the head
Preheat the oven to 400°F (200°C).
Grease a baking dish with butter.
Place the cleaned cod's head in the dish.
Add sweet herbs, onion with cloves, mace, pepper, bruised nutmeg, lemon peel, horseradish, and water.
Dust the head with flour.
Sprinkle grated nutmeg on top.
Dot with butter.
Sprinkle breadcrumbs over it.
Bake in the oven until cooked through.
Make the sauce
Transfer the head to a serving dish.
Keep the head warm over boiling water.
Pour the cooking liquid into a saucepan.
Boil for 3-4 minutes.
Strain the liquid.
Add red wine, ketchup, shrimp, oysters, mushroom pickle, and flour-rolled butter.
Stir.
Boil until thickened.
Pour the sauce over the cod's head.
Garnish and serve
Garnish with toasted bread, parsley, lemon, 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 cooked flesh and stock their flavour.
- Butter
- Adds richness and fat, and browns the breadcrumb topping in the oven.
- Flour
- Thickens the sauce when rolled into butter and stirred into the boiling liquid.
- Red wine
- Adds acidity and depth, balancing the richness of the sauce.
- Oysters
- Add briny flavour and a soft, tender texture to the sauce.
- Shrimp
- Add sweet, briny flavour and body to the sauce.
The step that matters
Boil the sauce until thickened. Flour-rolled butter only thickens once it reaches a boil, and boiling too long can make the sauce tight or reduce it too far. Watching for a smooth, lightly coating consistency keeps the sauce right.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (butter, clove, mace, white pepper, nutmeg, lemon, horseradish):

- Capsicumbetter flavor fit
- 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).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
