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, soy, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)

Also mentioned in the method: fish

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Fill a baking dish with water and add onion, lemon peel, horseradish, pepper, mace, and nutmeg.

  2. Plunge the fish into the water, flour the exposed parts, and dot with butter.

Bake and make the sauce

  1. Bake in a 350°F (175°C) oven until cooked through.

  2. Transfer the fish to a clean dish and pour the cooking liquid into a saucepan.

  3. Add wine or vinegar, chopped oysters, ketchup or soy, and butter to the saucepan.

  4. Stir until boiling, then pour over the fish.

Garnish and serve

  1. Garnish with fried bread and sliced lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Fish head (in the method)
Forms the main body of the dish, cooking through in the baking dish.
Flour
Coats the exposed fish, helping it brown and giving the sauce body.
Butter
Adds richness and moisture, melting over the fish and into the sauce.
Oysters
Contribute a briny, savoury flavour to the sauce.
Wine or vinegar
Adds acidity that brightens the flavour of the sauce.

The step that matters

Stir the sauce until boiling. Flour-thickened butter and liquid must be brought to a boil while stirred, or the sauce can stay lumpy and taste raw. Boiling also cooks off the raw starch taste.

Flavor stand-ins for the onion

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

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

Fit is the average pairing score against clove, lemon, horseradish, pepper, mace, nutmeg, flour. 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).
