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, with Tench and Eels
Ingredients
Directions
The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Clean and bone the tench; skin and bone the eels; cut them into 2‑inch pieces, leaving the sides of the tench whole.
Combine the bones, onions, herbs, mace, anchovies, water, and seasoning in a saucepan and simmer gently for 1 hour.
Strain the mixture, let it cool, and skim off the fat.
Assemble and bake
Layer the tench and eels in a pie dish, adding seasoning, chopped parsley, and hard‑boiled egg yolks between each layer.
Pour in part of the strained liquid, cover with puff pastry, and bake for about 30‑40 minutes at 400 °F (200 °C).
When done, heat the remaining liquid and pour it into the pie.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tench
- Forms the main body of the pie, with firm white flesh that holds its shape when baked.
- Eels
- Adds rich, fatty flesh that becomes tender and moist during the cooking.
- Hard-boiled egg yolks
- Add richness and a crumbly texture that thickens the filling slightly.
- Puff pastry
- Forms a flaky, golden crust that browns in the hot oven.
The step that matters
Skimming and straining the stock. Fat left in the liquid can make the pie greasy and cloudy, so it should be skimmed off after cooling and the stock strained clean before it goes into the pie.
Swap the mace
How well each one fits the dish's main ingredients (onion, pepper, parsley, egg):
- Thymefits better
- Dillfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against onion, pepper, parsley, egg. 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.
