Trout, Baked

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Clean, scale, empty, and dry the trout.

  2. Prepare the forcemeat and stuff it inside the trout, then sew up the openings.

Bake

  1. Place the fish in a baking dish with 2 oz of butter and bake at 350 °F (175 °C) for about 1 hour, basting frequently.

Make the sauce and serve

  1. In a pan, fry the flour and remaining butter together.

  2. Once the fish is ready, transfer it to a serving dish and strain the baking liquid into the flour and butter mixture.

  3. Stir until it boils and becomes smooth, then add the capers, lemon juice, and anchovy essence, seasoning to taste.

  4. Simmer for 2–3 minutes, then pour the sauce over the fish and serve.

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

What each ingredient does

Trout
Forms the main body of the dish, cooked whole and stuffed.
Butter
Adds richness and moisture while the fish bakes and forms the base of the sauce.
Flour
Thickens the baking liquid into a smooth sauce when cooked with the butter.
Capers
Add a sharp, briny note that balances the rich butter sauce.
Anchovy essence
Adds a savoury, salty depth to the sauce.

The step that matters

Stir the sauce until smooth before adding the flavourings. Flour mixed with hot butter and liquid can form lumps if not stirred constantly while it comes to the boil. Lumps stay in the sauce and are hard to remove later, so the sauce should be smooth before the capers, lemon and anchovy go in.
