Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Middle cod
- Forms the main body of the pie and is flaked into tender pieces when cooked.
- Flour
- Thickens the cream and broth mixture into a smooth, sauce-like consistency.
- Cream
- Adds richness and body to the sauce, softening its flavor.
- Butter
- Adds fat for richness and helps carry flavor through the dish.
- Pie crust
- Encloses the fish so it cooks in steam, keeping it moist under the pastry.
The step that matters
Bring the sauce to a boil while whisking. Flour thickens only when heated, and it can clump if added to liquid without being whisked smoothly. Bringing the mixture to a boil activates the starch so the sauce turns smooth and thick rather than lumpy or thin.
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.
