Why it works: Parsley and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 774 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Fish, with Herb Sauce
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
Preheat the oven to 350°F (175°C).
Grease a flat baking tin and lay down two fish fillets.
Spread half of the thick white sauce over the fillets.
Layer the other two fillets on top and cover with greased paper.
Bake and brown
Cook until the fish is almost done, then remove the paper.
Spread the remaining sauce on top, sprinkle with salt, nutmeg, coralline pepper, and breadcrumbs.
Drizzle with oiled butter and brown in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flat fish fillets
- Form the main body of the dish, cooking gently to a flaky texture under the sauce.
- Thick white sauce
- Keeps the fish moist during baking and forms a creamy layer between and over the fillets.
- Browned breadcrumbs
- Add a crisp, golden crust through browning on the surface.
- Oiled butter
- Carries fat to the surface, promoting browning and a rich flavour.
The step that matters
Removing the paper before the fish is fully cooked. The paper traps steam so the fish cooks gently and stays moist. Removing it only when the fish is almost done lets the top dry and brown without overcooking the flesh beneath.
Swap the onion
How well each one fits the dish's main ingredients (fish, sauce, parsley, chervil, nutmeg, pepper, butter):
- Shallotfits better
- Chivefits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against fish, sauce, parsley, chervil, nutmeg, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
