Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Creamed Fish
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Cook the fish in gently boiling water for 15–20 minutes.
Remove the flesh from the bones and flake it.
Season the fish with salt, pepper, and lemon juice.
Make the sauce
In a saucepan, melt the butter, add flour, and stir in the milk with the onion and salt.
Bake and serve
Pour the sauce over the fish and mix well.
Transfer to a platter, sprinkle with buttered bread crumbs, and bake at 400 °F (200 °C) for 20–30 minutes.
Add a speck of cayenne to the sauce if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whitefish
- Provides the main body and flaky texture of the dish.
- Butter
- Adds richness and flavor and forms the base of the sauce.
- Flour
- Thickens the milk into a smooth, creamy sauce as its starch cooks.
- Milk
- Forms the liquid base of the sauce, giving it its creamy texture.
The step that matters
Making the sauce. Flour must be cooked in the melted butter and whisked into the milk so its starch dissolves evenly. Adding the milk gradually while stirring prevents lumps, and heating the mixture lets the starch swell and thicken the sauce.
Swap the onion
How well each one fits the dish's main ingredients (whitefish, pepper, lemon, butter, flour, milk, bread):
- Capsicumfits better
- Shallotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against whitefish, pepper, lemon, butter, flour, milk, bread. Candidates are from the same food group and used in at least 100 recipes.
