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 ↓

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 filling
Scald the milk in a saucepan.
Stir in the grated bread crumbs and cook for 1 minute.
Remove from heat and add parsley, egg yolks, cayenne, paprika, salt, and onion juice. Mix well and fold in the flaked fish.
Fill and bake
Fill shells or individual dishes with the mixture.
Top with buttered bread crumbs and brown in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Softens the bread crumbs into a moist, creamy base for the filling.
- Grated bread crumbs
- Thicken the milk and give the filling body and structure.
- Egg yolks
- Enrich the filling and help it set firm when heated.
- Flaked cooked fish
- Forms the main body of the filling and adds savory flavor.
- Onion juice
- Adds a sharp, aromatic onion flavor to the filling.
The step that matters
Browning the buttered bread crumb topping. The filling is already cooked, so the oven mainly browns the topping. Watch it closely, since the buttered crumbs can scorch before the filling heats through.
Swap the onion
How well each one fits the dish's main ingredients (milk, bread, parsley, egg, pepper, fish):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against milk, bread, parsley, egg, pepper, fish. Candidates are from the same food group and used in at least 100 recipes.
