Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,122 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish a LA Creme
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 the fish
Boil the fish in salted water until cooked.
Remove the skin, bones, and shred the fish finely.
Make the sauce
In a bowl, mix the cream, flour, butter, onion, parsley, and cayenne pepper until well combined.
Assemble and bake
In a deep dish, layer the shredded fish and sauce until the dish is filled.
Top with bread crumbs and bake at 350°F (175°C) for 30 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut, whitefish, rock or shad
- Provides the flaky body of the dish once cooked and shredded.
- Cream
- Forms the rich sauce that moistens the fish and carries the flavor.
- Flour
- Thickens the cream into a sauce that holds the fish together.
- Butter
- Adds richness and fat to the sauce, improving mouthfeel and flavor.
- Bread crumbs
- Forms a crisp, browned topping during baking.
The step that matters
Make the sauce with flour. Flour must be thoroughly mixed into the cream and butter so it hydrates evenly; lumps stay raw-tasting and the sauce will not thicken smoothly in the oven.

Fit is the average pairing score against whitefish, cream, flour, butter, parsley, pepper, bread. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“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.
