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.
Bake
Preheat the oven to 400°F (200°C).
Rub a baking dish with butter and place the cleaned cod's head inside.
Add sweet herbs, onion, mace, pepper, bruised nutmeg, lemon peel, horseradish, and water.
Dust the cod's head with flour, grate nutmeg over it, and dot with butter.
Sprinkle breadcrumbs over the top and bake in the oven.
Once cooked, transfer the cod's head to a serving dish and keep warm over boiling water.
Make the sauce
Pour the cooking liquid into a saucepan and boil for 3-4 minutes.
Strain the liquid and add red wine, ketchup, shrimp, oysters, mushroom pickle, and butter.
Stir well and boil until thickened, then strain again and pour over the cod's head.
Garnish and serve
Garnish with toasted bread, 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
- Main protein, gently cooked in liquid so it stays moist and tender.
- Butter
- Adds richness and helps the surface brown in the oven.
- Flour
- Dusted on the fish and used to help thicken the sauce.
- Red wine
- Adds acidity and depth to the sauce.
- Shrimp
- Add a sweet, briny seafood flavour to the sauce.
- Oysters
- Add a briny, savoury seafood flavour to the sauce.
The step that matters
Boiling the sauce until thickened. Boiling evaporates water and concentrates the liquid, while flour and butter thicken it. Boiling too hard or too long can over-reduce the sauce or scorch it, and stirring helps prevent sticking.

- 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.
