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
Salt the cod well and let it sit overnight.
The next day, wash the cod and season it with pepper, salt, and nutmeg.
Bake and serve
Place the cod in a dish, add butter, and pour in the broth.
Cover the dish with pastry and bake until done.
For the sauce, mix broth, cream, flour, and butter, then add lemon zest before serving.

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 gives it its flaky, savory filling.
- Butter
- Adds richness and moisture to the fish and helps the sauce become silky.
- Flour
- Thickens the sauce so it holds together rather than running thin.
- Cream
- Adds richness and body to the sauce, softening its flavor.
The step that matters
Salting the cod overnight. Salt draws out and then reabsorbs moisture, seasoning the fish through and firming its texture. Too little time or salt leaves the cod bland, while too much makes it overly salty and tough, so the timing and amount both matter.

Fit is the average pairing score against pepper, nutmeg, butter, cream, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
