Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky, tender main body of the pie filling.
- Butter
- Adds fat and richness, carrying flavour through the cod.
- Cream or milk
- Adds moisture and a smooth, creamy texture to the sauce.
- Thickening (flour or butter)
- Thickens the liquid so the sauce holds together rather than running off.
- Oysters
- Contribute a briny, savoury flavour to the sauce.
- Stock
- Provides liquid and savoury depth to the filling and sauce.
The step that matters
Bring the sauce to a boil.. Flour thickening only reaches full strength once the sauce boils, as starch granules swell and gelatinise. Undercooked sauce stays thin and can taste floury, so it should be boiled until it has visibly thickened.
Swap the mace
How well each one fits the dish's main ingredients (pepper, nutmeg, butter, sauce, cream, flour, lemon):
- Parsleyfits better
- Tarragonfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against pepper, nutmeg, butter, sauce, cream, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
