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.

Make the stock

  1. In a stewpan, combine the bones of the tench and eels, onions, thyme, parsley, mace, anchovies, and stock or water.

  2. Bring to a boil over low heat for 1 hour, then strain and skim the fat.

  3. Cool the liquid, then place the tench and eels in a dish.

Assemble the pie

  1. Season with pepper, coarse sea salt, chopped parsley, and add whole mushrooms and egg yolks.

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

  3. Roll out puff pastry and place it around the edge of the dish, covering it.

  4. Before baking, brush the top of the pie with egg.

Bake and serve

  1. Bake in a preheated oven at 400°F (200°C) for about 30 minutes.

  2. When the pastry begins to color, pour some liquid over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tench
Forms the flaky, meaty body of the pie filling.
Eels
Adds rich, firm pieces that hold their texture during baking.
Puff pastry
Forms a crisp, layered crust that rises and browns in the oven.
Egg yolks
Enrich the filling and help the glazed top brown.
Anchovies
Add savory depth to the stock, rounding out its flavor.

The step that matters

Cool the liquid before assembling. Adding the stock to the fish while it is still hot can overcook the delicate flesh and make the filling watery; cooling it first keeps the fish tender and the pastry crust from becoming soggy.

Swap the mace
