Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky main body of the pie, cooked gently within the crust.
- Cream
- Adds richness and a smooth, silky texture to the sauce.
- Flour
- Thickens the sauce so it clings to the fish instead of running thin.
- Broth
- Provides savoury liquid that moistens the fish and forms the base of the sauce.
- Butter
- Adds fat for richness and flavour in both the fish and the sauce.
The step that matters
Bring the sauce to a boil. Flour only thickens fully once the starch granules swell in boiling liquid. Stopping short leaves the sauce thin and pasty-tasting, while stirring prevents lumps and scorching on the base of the pan.
Swap the lemon
How well each one fits the dish's main ingredients (pepper, nutmeg, butter, cream, flour, sauce, oyster):
- Lemonthe original

- Raisinfits about as well
- Avocadofits less well
Fit is the average pairing score against pepper, nutmeg, butter, cream, flour, sauce, oyster. Candidates are from the same food group and used in at least 100 recipes.
