Fish Pie, with Tench and Eels

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 stock

  1. Clean and bone the tench, skin and bone the eels, and cut them into 2‑inch pieces, leaving the sides of the tench whole.

  2. Combine the bones, onions, herbs, mace, anchovies, water, pepper, and salt in a pot.

  3. Simmer gently for 1 hour.

  4. Strain the mixture.

  5. Let the strained liquid cool.

  6. Skim off the fat from the cooled liquid.

Assemble and bake

  1. Layer the tench and eels in a pie dish, seasoning each layer with salt, pepper, chopped parsley, and hard‑boiled egg yolks.

  2. Pour some of the strained liquid over the fish.

  3. Cover the fish with puff pastry.

  4. Bake at 400°F (200°C) for about 1 hour.

Serve

  1. Heat the remaining liquid.

  2. Pour the heated liquid into 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
Forms the main flaky fish body of the pie.
Eels
Adds rich, firm fish pieces that hold their shape during baking.
Puff pastry
Forms a crisp, golden, buttery crust that browns in the oven.
Hard-boiled eggs
Yolks add richness and a creamy texture to the filling.
Anchovies
Contribute savory depth to the stock, boiled into the liquid.

The step that matters

Skim off the fat from the cooled liquid. Fat left on the stock can make the pie greasy and cloudy. Chilling the liquid lets the fat rise and solidify so it can be lifted off cleanly.

Swap the mace

How well each one fits the dish's main ingredients (onion, pepper, parsley, egg):

  1. Thymefits better
  2. Dillfits better
  3. Tarragonfits better
  4. 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.
