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 Fish
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, wipe, and dry the fish.
Rub the fish with coarse sea salt, stuff it, and sew it closed.
Cut gashes two inches apart on each side and skewer the fish into the shape of an 'S'.
Place the fish on a baking sheet and rub it all over with soft butter, salt, and pepper.
Insert narrow strips of fat salt pork into the gashes and dredge the fish well with flour.
Bake and serve
Bake in a hot oven (400°F / 200°C) without water, basting when the flour is brown and often afterward.
Remove the strips of pork, skewer, or strings when done, and wipe off all fat or water.
Place the fish on a hot platter and pour Hollandaise sauce around it or serve drawn butter sauce in a sauce boat.
Pile Saratoga chips around the fish and garnish the head with parsley or watercress.

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, cooked whole so it stays moist inside the skin.
- Flour
- Dredged on the outside, it browns in the oven to create a golden, crisp crust.
- Butter
- Rubbed over the fish, it adds richness and helps the surface brown and taste savoury.
- Fat salt pork
- Inserted into the gashes, it melts during baking, moistening the flesh and adding savoury flavour.
The step that matters
Basting after the flour browns. Basting only once the flour turns brown keeps the crust from scorching early while still building colour. Repeated basting then keeps the surface moist and evenly browned as the fish cooks through.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, pepper, pork, flour, parsley, capers):

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