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 with Tench
Ingredients
Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Skin and bone the eels, then clean and bone the tench.
Cut the eels into 2-inch pieces and leave the tench whole.
Make the liquid
Put the bones and trimmings in water and stew for 1 hour.
Strain the liquid, remove the fat, and boil with onions, mace, anchovies, pepper, salt, and herbs.
Assemble and bake
Layer the eels, tench, hard-boiled eggs, and parsley in a dish.
Pour in enough of the prepared liquid to cover the fish.
Cover with puff pastry and bake at 400 °F (200 °C) for about 35 minutes.
Add more liquid after baking if desired.

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
- Eels
- Firm, rich fish that forms the main body of the pie filling.
- Tench
- Mild white fish that adds flakiness and bulk to the filling.
- Anchovies
- Dissolve into the liquid, adding savoury depth without a clearly fishy taste.
- Hard-boiled eggs
- Add a firm, creamy texture and mild richness to the layers.
- Puff pastry
- Bakes into flaky, crisp layers that seal and brown the top of the pie.
The step that matters
Cover the fish with the liquid before baking. Fish dries and toughens in the oven if exposed. Enough liquid keeps the fish moist and gives the filling its sauce while the pastry bakes.
Swap the mace
How well each one fits the dish's main ingredients (onion, pepper, egg, parsley):
- Thymefits better
- Dillfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against onion, pepper, egg, 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.
