Why it works: Nutmeg and mace 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: egg, milk, wheat, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the fish
Strew salt on the cleaned cod's head.
Place the head in a tin oven or stewpan before the fire.
After 30 minutes, drain off the water and season with nutmeg, cloves, beaten mace, and salt.
Flour and baste with butter, then let it stand before turning and basting the other side.
Repeat basting often and sprinkle with bread crumbs.
Make the sauce and serve
For the sauce, melt butter and mix with an anchovy, boiled and bruised liver, and beaten egg yolks.
Strain the sauce, return it to the saucepan, and add shrimps or pickled cockles, port wine, and lemon juice.
Simmer for 1-2 minutes, then pour the sauce over the roasted cod's head and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod's head
- The main fish, which is roasted until cooked through and browned on the outside.
- Butter
- Adds richness and moisture while basting, and browns the surface of the fish.
- Bread crumbs
- Sprinkled on the fish to form a crisp, browned crust.
- Egg yolks
- Emulsify with the melted butter and thicken the sauce as they set gently with heat.
- Anchovy
- Adds a salty, savoury depth to the sauce.
- Lemon juice
- Adds acidity that brightens the rich, buttery sauce.
The step that matters
Adding the egg yolks to the sauce. Egg yolks thicken when gently heated but can scramble if the sauce gets too hot. Keep the heat low and stir constantly, so the sauce turns smooth and silky rather than curdled.

Fit is the average pairing score against nutmeg, mace, butter, bread, egg, anchovy, port wine. 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).
