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.
Place the cod in a dish, add butter, and pour in some broth.
Bake and finish
Cover with pie crust and bake until done.
For the sauce, combine broth, cream, flour, butter, lemon zest, and nutmeg in a pot.
Bring the sauce to a boil and pour it into the pie through a hole in the center.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky, savory filling that the pie is built around.
- Cream
- Adds richness and a smooth, silky texture to the sauce.
- Flour
- Thickens the sauce so it sets to a spoonable consistency.
- Butter
- Adds fat and rich flavor to the fish and the sauce.
- Broth
- Adds savory liquid that moistens the fish and flavors the sauce.
The step that matters
Bring the sauce to a boil. Flour thickens only when it is heated enough for its starch granules to swell, so the sauce must reach a full boil to set properly.
Swap the lemon
How well each one fits the dish's main ingredients (pepper, nutmeg, butter, sauce, cream, flour, oyster):
- Lemonthe original
- Limefits about as well
- Raisinfits about as well
- Avocadofits less well
Fit is the average pairing score against pepper, nutmeg, butter, sauce, cream, flour, oyster. Candidates are from the same food group and used in at least 100 recipes.
