Baked Haddock

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Preheat the oven to 350°F (175°C).
Stuff the haddock with sausage and sew it up.
Truss the haddock into the shape of an 'S'.
Brush the top with beaten egg and sprinkle with bread crumbs.
Bake for 30 minutes, basting frequently with dripping.
Serve with melted butter.
