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 (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the fish
Wash the cod's head and shoulders well and cut off the fins.
Pour boiling water over the fish to loosen the black scales.
Scrape the scales off until the skin is white.
Wash the fish in cold water.
Boil the fish in salted water for 15 minutes.
Coat and bake
Place the boiled fish on a dish and rub it with the yolks of 2-3 beaten eggs.
Sprinkle the fish with bread crumbs mixed with pepper and minced parsley.
Dot the fish with small pieces of butter.
Place the fish in the oven to brown.
Make the sauce
In a saucepan, mix flour with butter.
Add gravy, white wine, pepper, salt and nutmeg to the mixture.
Heat the sauce until combined.

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 help it brown on the fish.
- Bread crumbs
- Form a crisp, browned crust over the fish surface.
- Butter
- Adds fat and richness, and helps the crust brown as it melts.
- Flour
- Thickens the butter and gravy into a smooth sauce.
- Gravy
- Forms the liquid base of the sauce and adds savoury depth.
- White wine
- Adds acidity and aroma to the sauce.
The step that matters
Place the fish in the oven to brown. The coating of egg yolk, crumbs and butter can burn or dry out before the fish is heated through if the oven is too hot or the fish is left too long. Watch the colour closely and stop once the crust is golden.

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).
