Ingredients

Directions

The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.

Prepare the fish

Wash, dry, and cut the fish into nice pieces.
Stew the fish in a little cold water and salt to make gravy.

Assemble and bake

Layer the fish in a pie dish, sprinkling each layer with salt, pepper, parsley, and browned crumbs.
Pour the gravy over the fish and let it cool.
Cover with pastry and bake in a hot oven (400°F / 200°C) for about 30 minutes.
