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 ↓
Cream Fish
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 for about 20 minutes.
Remove the skin and flake the fish, discarding the bones.
Make the sauce
Boil the milk in a saucepan.
Mix the butter and flour together, then gradually stir in the hot milk.
Add parsley, chopped onion, salt, and pepper to the mixture.
Stir on the stove until the sauce thickens.
Bake and serve
Butter a deep dish and layer in the flaked fish and sauce until all ingredients are used, with sauce on top.
Sprinkle the top with bread crumbs and a little butter.
Bake at 350°F (175°C) for 30 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the bulk of the dish, providing the flaked meat that the sauce coats.
- Milk
- Forms the liquid base of the sauce, giving it body and a creamy texture.
- Butter
- Adds richness and fat, and with the flour forms the roux that thickens the sauce.
- Flour
- Thickens the milk into a smooth sauce by swelling as it cooks with the butter.
- Bread crumbs
- Form a crisp, browned topping when baked over the sauce.
The step that matters
Stir the sauce until it thickens. Flour must be fully cooked in the hot milk and fat to thicken smoothly and lose its raw taste. Adding hot milk gradually and stirring constantly prevents lumps from forming.
Swap the onion
How well each one fits the dish's main ingredients (fish, milk, butter, egg, flour, parsley, pepper):
- Potatofits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against fish, milk, butter, egg, flour, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
“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.
