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 ↓
Eel 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
Preheat the oven to 350°F (175°C).
Line a dish with potato paste.
Assemble the pie
Place the cut eels in the dish and season with pepper, coarse sea salt, parsley, and butter.
Pour a little stock or a few tablespoons of gravy over the eels.
Add a spoonful of mushroom catsup and dredge with flour.
Cover with potato paste and bake for 1 hour and 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main filling, becoming tender and flavorful as they cook slowly in the pie.
- Potato paste
- Forms the crust that encloses the filling and holds in moisture while baking.
- Butter
- Adds richness and fat, helping the filling taste rounded and carry flavor.
- Flour
- Dusted over the filling, it thickens the cooking liquid into a slightly saucy binder.
- Stock or gravy
- Supplies liquid that gently steams the eels and forms the sauce within the pie.
- Mushroom catsup
- Adds concentrated savory, umami depth to the filling and its sauce.
The step that matters
Covering with potato paste before baking. The sealed crust traps steam so the eels cook gently in their own juices and liquid. Leaving gaps lets moisture escape, so the filling can dry out or the sauce can thin.
Swap the potato
How well each one fits the dish's main ingredients (pepper, parsley, butter, mushroom, flour):

- Potatothe original
Fit is the average pairing score against pepper, parsley, butter, mushroom, flour. Candidates are from the same food group and used in at least 100 recipes.
