Why it works: Parsley and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Baked White Fish or Trout
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Clean the fish by letting boiling water run through its mouth and eye sockets.
Gash the skin at intervals of 2 inches and insert slips of salt pork.
Rub the fish with salt, pepper, and soft butter, then dredge lightly with flour.
Skewer the fish in a '0' or 'S' shape and place it on a bed of pork chips on a fish sheet.
Bake and serve
Bake in a hot oven (400°F / 200°C) without water in the dripping pan.
Baste often with fat from the pork or a little melted butter.
Serve on a folded napkin, garnished with parsley and Saratoga chips.

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 in the oven to become flaky.
- Salt pork
- Renders fat into the fish as it bakes, keeping the flesh moist and adding savour.
- Soft butter
- Adds fat that enriches the flesh and helps it brown lightly on the surface.
- Flour
- Light dusting that helps the skin brown and gives the surface a slightly crisp finish.
The step that matters
Basting often. Fish is lean and dries out quickly in a hot oven. Regular basting with melted fat coats the surface, keeping the flesh moist while the skin browns.
Swap the onion
How well each one fits the dish's main ingredients (fish, pork, pepper, butter, flour, parsley, capers):
- Shallotfits better
- Chivefits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against fish, pork, pepper, butter, flour, parsley, capers. Candidates are from the same food group and used in at least 100 recipes.
