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 the fish
Clean and bone the tench.
Skin and bone the eels.
Cut the fish into 2-inch pieces, leaving the sides of the tench whole.
Make the stock
Combine the bones, onions, herbs, mace, anchovies, water, and seasoning in a saucepan.
Simmer gently for 1 hour.
Strain the mixture.
Let the strained liquid cool.
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 part of the strained liquid into the pie.
Cover the pie with puff pastry.
Bake for 30-40 minutes in a hot oven (400°F/200°C).
Serve
Heat the remaining liquid.
Pour the heated liquid into the pie before serving.

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 flesh that holds its shape during baking.
- Eels
- Adds richness and fat to the filling, giving it a fuller, more savoury flavour.
- Hard-boiled egg yolks
- Add a rich, creamy texture between the fish layers.
- Anchovies
- Build savoury depth in the stock, adding a salty, umami note.
- Puff pastry
- Forms a crisp, flaky crust that browns in the hot oven.
The step that matters
Skim off the fat from the stock. Fat left in the cooled liquid can make the pie greasy and can separate in the sauce, so removing it keeps the filling clean-tasting.
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.
