Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the pie, becoming flaky and opaque as it cooks.
- Cream
- Adds richness and a smoother, silkier texture to the sauce.
- Flour
- Thickens the sauce as it heats with the liquid and fat.
- Pie crust
- Encloses the fish, trapping steam so it cooks gently while the crust browns.
- Broth
- Provides moisture and savory flavor for both the fish and the sauce.
The step that matters
Bring the sauce to a boil. Flour needs to reach a boil, with stirring, to fully thicken and lose its raw starchy taste. Stopping early leaves the sauce thin and pasty.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (pepper, nutmeg, butter, cream, flour, lemon, oyster):
- Parsleythe original
- Marjoramfits about as well
- Cinnamonfits about as well
- Tarragonfits less well
Fit is the average pairing score against pepper, nutmeg, butter, cream, flour, lemon, oyster. Candidates are from the same food group and used in at least 100 recipes.
