Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Fish Pie, with Tench and Eels, and Hard Eggs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish and stock
Clean and skin the tench and eels, bone the tench, and cut the eels into 2‑inch pieces.
In a stewpan, combine the bones of the tench and eels, onions, thyme, parsley, mace, anchovies, and stock or water.
Bring to a boil and simmer slowly for 1 hour, then strain and skim the fat.
Assemble and bake
In a dish, place the eel and tench, season with pepper, salt, and chopped parsley, and add mushrooms and egg yolks.
Pour some of the strained liquid over the fish, then cover the dish with puff pastry, sealing the edges.
Brush the top with egg wash before baking.
Bake in a preheated oven at 400 °F (200 °C) for about 30 minutes, until the pastry is golden.
Pour the remaining hot liquid over the pie before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tench
- Provides the main firm, flaky white fish that forms the body of the pie.
- Eels
- Give rich, oily flesh that stays moist and tender during baking.
- Hard boiled egg yolks
- Add richness and a crumbly, creamy texture to the filling.
- Puff pastry
- Forms a crisp, layered, golden crust that seals in the filling.
- Anchovies
- Dissolve into the stock to add savoury depth and umami.
The step that matters
Simmering the fish stock. Simmering gently for the full hour extracts gelatin and flavour from the bones without clouding the liquid. Boiling hard can break up the stock and make it cloudy and greasy, weakening the sauce that finishes the pie.
Swap the mace
How well each one fits the dish's main ingredients (onion, thyme, parsley, pepper, mushroom, egg):
- Marjoramfits better
- Winter savoryfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against onion, thyme, parsley, pepper, mushroom, egg. Candidates are from the same food group and used in at least 100 recipes.
