Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked Fish
Ingredients
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
Wash the fish carefully.
Sprinkle the fish with coarse sea salt.
In a bowl, mix bread crumbs with salt, pepper, chopped onion, and butter.
Stuff the mixture into the fish and secure it to keep it together.
Bake
Place the fish in a baking pan with 1 pint of water.
Season the fish with salt, pepper, and butter.
Dredge the fish with flour.
Bake at 350°F (175°C) for 1.5 hours, basting frequently.
Garnish and serve
Once done, garnish with sliced hard-boiled eggs and parsley.
Serve with potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking through to become flaky and tender.
- Bread crumbs
- Absorb juices from the fish and bind the stuffing so it holds together.
- Butter
- Adds fat and richness, helping the fish stay moist and carry flavour.
- Flour
- Dredging coats the surface, helping it brown and form a light crust.
- Onion
- Adds aromatic flavour to the stuffing as it softens during baking.
The step that matters
Basting frequently during the bake. Regular basting spoons hot liquid over the fish, keeping the surface moist while it cooks through, so the flesh stays tender rather than drying out over the long bake.
Swap the onion
How well each one fits the dish's main ingredients (fish, pepper, bread, butter, flour, egg, parsley):

Fit is the average pairing score against fish, pepper, bread, butter, flour, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
