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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the cod
Lay the cod in salt for 4 hours, then wash it and place it in a dish.
Season the cod with pepper and salt, then add the butter and stock.
Bake the pie
Cover the cod with the paste crust and bake at 400°F (200°C) for 1 hour.
Make and add the sauce
Mix the stock, cream or milk, and thickening for the sauce.
Add lemon peel to the sauce and bring it to a boil.
Pour the sauce into the pie through a hole in the crust.
Cover the sauce with a small piece of pastry shaped like a leaf.

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, becoming flaky and tender when baked.
- Butter
- Adds richness and moisture to the fish as it bakes.
- Cream or milk
- Gives the sauce body and a smooth, rich texture.
- Flour or butter thickening
- Thickens the stock and cream into a sauce that holds its shape.
- Paste crust
- Encloses the fish and sauce, sealing in moisture while the pie bakes.
The step that matters
Pouring the sauce through the crust. The sauce must be hot and well thickened before it goes in, so it pours easily and does not thin the fish or leave the crust soggy.
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.
