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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky main filling that the pie is built around.
- Butter
- Adds richness and carries flavor through the fish and sauce.
- Flour
- Thickens the sauce so it clings to the fish rather than running off.
- Cream
- Adds body and a smooth, rich texture to the sauce.
- Pie crust
- Encloses the fish and steam so it cooks gently under cover.
The step that matters
Bring the sauce to a boil before pouring it in. Flour only thickens fully once it reaches a boil, so a sauce that is not brought to a boil stays thin and runny in the pie.
Swap the lemon
How well each one fits the dish's main ingredients (pepper, nutmeg, butter, cream, flour):

- 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.
