Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Baked Fish
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Place the cleaned and dried fish in a well-oiled baking pan.
Brush the fish with oil or melted butter.
Sprinkle salt, pepper, minced parsley, and flour over the fish.
If using a whole fish, place a slice of onion, a slice of lemon, and a bay leaf inside.
Bake
Bake in the oven, basting occasionally with hot water and butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Dusted over the fish, it helps form a light crust and holds in surface moisture.
- Oil or melted butter
- Coats the skin, helping it brown and keeping the fish from drying out.
- Fish
- The main protein; it cooks through in the oven and becomes flaky.
The step that matters
Basting during the bake. Basting with hot liquid and butter transfers heat to the surface and keeps the fish moist. Opening the oven often to baste lets heat escape and can slow cooking, so baste occasionally rather than constantly.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, pepper, parsley, flour, lemon):
- Shallotfits better
- Carrotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against fish, butter, pepper, parsley, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
