Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cod Pie
Ingredients
Directions
Prepare the cod

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 and provides its flaky texture.
- Butter
- Adds richness and fat, helping the cod stay moist and the sauce turn silky.
- Flour
- Thickens the sauce so it holds together rather than running thin.
- Cream
- Adds body and richness to the sauce.
- Broth
- Provides liquid that moistens the cod and forms the base of the sauce.
The step that matters
Salting the cod overnight. Salt draws moisture out of the fish and then lets it be reabsorbed, seasoning the flesh through and firming its texture. Skipping the rest or rinsing poorly leaves the fish either bland or overly salty, so the wash the next day matters.

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.
