Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish Turbot in Shells
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sauce
Scald the cream in a saucepan.
In a separate bowl, rub together the butter and flour until smooth.
Add the butter‑flour mixture to the scalded cream and stir until it thickens.
Add the bread crumbs and cook over low heat for 5 minutes, stirring occasionally.
Assemble and bake
Remove from heat and gently mix in the fish, parsley, salt, and pepper.
Fill greased scalloped shells or individual souffle dishes with the mixture.
Brush the tops with beaten egg yolk and bake in a preheated oven at 400°F (200°C) until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream or milk
- Forms the liquid base of the sauce that binds the filling together.
- Flour
- Thickens the cream into a smooth sauce when cooked with butter.
- Butter
- Adds richness and helps make the flour roux smooth.
- Bread crumbs
- Absorb liquid and add body so the filling holds its texture.
- Cooked fish
- Provides the main filling and flavor of the dish.
- Hard-boiled egg yolks
- Add richness and help bind and enrich the filling.
The step that matters
Thickening the cream with the butter‑flour mixture. Flour must be cooked in the hot cream long enough to swell and set the sauce; adding it lumpy or undercooking leaves a raw, pasty texture and a thin filling that won't hold in the shells.
Swap the parsley
How well each one fits the dish's main ingredients (egg, cream, bread, fish, butter, flour, pepper):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Tarragonfits about as well
Fit is the average pairing score against egg, cream, bread, fish, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
