Why it works: Fish and oyster match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 488 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
The recipe
Ingredients
Contains: wheat, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Wipe the cod slices with a clean cloth.
Dip each slice in flour.
Fry the slices in clarified dripping for 10 to 15 minutes, depending on thickness.
Drain the fried cod and place on a dish.
Cover with slightly thickened and browned meat gravy flavored with onion and herbs.
Add capers, mushrooms, or oysters to the gravy for extra flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Flavor stand-ins for the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (fish, flour, meat, onion, parsley, mushroom, oyster):
- Thymebetter flavor fit
- Garlicbetter flavor fit
- Celeryabout as good a flavor fit
- Capersthe original
Fit is the average pairing score against fish, flour, meat, onion, parsley, mushroom, 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).
