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.
Bake and serve
In a deep dish, layer the fish and sauce until 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
- Cream
- Forms the rich body of the sauce and keeps the fish moist during baking.
- Flour
- Thickens the cream into a sauce that clings to the fish.
- Butter
- Adds richness and fat that carries flavour and helps the sauce feel smooth.
- Halibut, whitefish, rock or shad
- Forms the main body of the dish, becoming tender once cooked and shredded.
The step that matters
Thickening the cream sauce with flour. Flour must be fully mixed into the cream and butter so it thickens evenly; lumps or undissolved starch leave the sauce grainy and uneven in the baked dish.
Flavor stand-ins for the onion

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.
