Why it works: Parsley and pepper 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: milk, wheat, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: breadcrumbs
Directions
Prepare the cod
Clean and trim the cod, then stuff it with veal stuffing and sew up the belly.
Truss the fish in an S shape and make several deep incisions on either side.
Place the cod in a deep baking dish greased with fresh butter.
Season and bake
Season with parsley, mushrooms, pepper, and salt.
Moisten with sherry and the liquor from the oysters.
Bake in the oven, basting every 10 minutes with its own juices.
When nearly done, sprinkle with breadcrumbs and return to the oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the dish, cooking into moist, flaky flesh.
- Veal stuffing
- Fills the cavity, adding richness and moisture as the fish bakes.
- Fresh butter
- Greases the dish and adds richness to the fish as it bakes.
- Sherry
- Moistens the fish, adding acidity and aroma as it cooks.
- Oyster liquor
- Adds briny moisture and savoury flavour to the cooking liquid.
- Breadcrumbs (in the method)
- Sprinkled on near the end, they brown into a golden crust.
The step that matters
Basting every 10 minutes with its own juices. Regular basting keeps the surface of the fish moist while the liquid reduces and concentrates flavour. Lean fish dries out quickly in dry oven heat, so skipping basting risks a tough, dry result.
Flavor stand-ins for the parsley

- Celeryabout as good a flavor fit
Fit is the average pairing score against veal, butter, mushroom, pepper, sherry, oyster. 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).
