Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Boil the potatoes in salted water until tender.
Soak the bread in cold water, then wring it dry in a clean towel; season with pepper, salt, and chopped parsley.
Cut the fish into small slices and soak in cold salted water.
Once the potatoes are done, peel and mash them, seasoning with salt and pepper.
Assemble and bake
Layer the fish and bread alternately in a pudding dish, then top with the mashed potatoes.
Bake the pie for one hour at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the pie, providing the savoury filling.
- Stale bread
- Soaked and wrung dry, it absorbs moisture and adds body to the filling.
- Potatoes
- Mashed to form a soft topping that cooks through and browns in the oven.
The step that matters
Wring the bread dry. Bread soaked in water holds a lot of liquid. If it is not squeezed dry, the excess moisture thins the filling and can make the pie soggy when it bakes.
Swap the potato
How well each one fits the dish's main ingredients (bread, pepper, parsley):
- Carrotfits better
- Capsicumfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against bread, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
