Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,118 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. 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

  1. Wash the cod's head and shoulders thoroughly and cut off the fins.

  2. Pour boiling water over the fish to loosen the black scales, then scrape them off until the skin is white.

  3. Wash the fish in cold water, then place it in boiling salt water and boil for 15 minutes.

Coat and bake

  1. Transfer the fish to a dish and rub it with the yolks of 2-3 beaten eggs.

  2. Sprinkle the fish with bread crumbs mixed with pepper and minced parsley, then dot with small pieces of butter.

  3. Place the fish in the oven to brown.

Make the sauce and serve

  1. In a saucepan, mix 1 tablespoon of flour with ¼ cup of butter, then add ½ cup of gravy, ⅓ cup of white wine, pepper, salt, and nutmeg.

  2. Mince the lobster meat and slightly brown the oysters in a frying pan, then add them and half their liquor to the gravy mixture.

  3. Heat the sauce and pour it around the fish on the dish.

  4. Garnish with cut lemon.

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

What each ingredient does

Egg yolks
Bind the crumb coating and add richness and gloss as the fish browns.
Butter
Adds richness and fat to the sauce and crumb topping, helping them brown.
Flour
Thickens the butter and gravy mixture into a smooth sauce.
Oysters
Add briny, savoury flavour and tender texture to the sauce.
Lobster
Adds sweet, delicate meat to the sauce.

The step that matters

Heat the sauce gently after adding the oysters. Flour-thickened sauces can lump if not whisked as they heat, and oysters overcooked in a hot sauce turn tough and rubbery, losing their delicate flavour.

Flavor stand-ins for the nutmeg

Fit is the average pairing score against egg, bread, pepper, parsley, butter, flour, white 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).
