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 filling that is the body of the pie.
- Cream
- Adds richness and moisture to the sauce, giving it a smooth texture.
- Flour
- Thickens the sauce as it heats, giving it body.
- Butter
- Adds fat and richness to the fish and the sauce.
The step that matters
Bringing the sauce to a boil. Flour needs to reach a boil to fully thicken the sauce. Stopping early can leave it thin and faintly raw-tasting, while boiling too hard after adding cream can cause it to split or scorch.
Swap the lemon
How well each one fits the dish's main ingredients (pepper, nutmeg, butter, cream, flour):
- Lemonthe original
- Raisinfits about as well
- Limefits about as well
- Coconutfits less well
Fit is the average pairing score against pepper, nutmeg, butter, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
