Why it works: Pepper and parsley 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
Boil the fish until cooked, then let it cool and pick it into pieces.
In a pot, boil the milk with the onion tied in a bag.
Make the sauce
Once the milk boils, stir in the butter and flour mixture until well combined.
Cook the sauce thoroughly, then season with salt, red pepper, and chopped parsley.
Assemble and bake
Mix the sauce with the fish, place in a baking dish, and sprinkle bread crumbs on top.
Bake in a preheated oven at 350°F (175°C) for a few minutes until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, held together in the creamy sauce.
- Milk
- Forms the liquid base of the sauce, giving it a creamy texture.
- Butter
- Adds fat and richness, and helps give the sauce a smooth mouthfeel.
- All-purpose flour
- Thickens the milk into a sauce as its starch swells when heated.
- Onion
- Infuses the milk with savory aroma while it is tied in a bag.
- Bread crumbs
- Form a crisp topping that browns in the oven.
The step that matters
Cooking the sauce thoroughly. Flour thickens only when its starch is heated enough to swell, and cooking it fully removes raw flour taste. Undercooked sauce can stay thin and taste pasty.
Swap the onion
How well each one fits the dish's main ingredients (fish, milk, butter, flour, pepper, parsley, bread):

- Onionthe original
Fit is the average pairing score against fish, milk, butter, flour, pepper, parsley, bread. Candidates are from the same food group and used in at least 100 recipes.
