Ingredients

Directions

The book says “a moderately hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Separate the salmon into large flakes.

  2. Place the flakes in a fireproof baking dish.

  3. Sprinkle with salt and pepper, then cover with sauce.

Top and bake

  1. Add a thin layer of lightly browned breadcrumbs.

  2. Dot with small pieces of butter on top.

  3. Bake at 400°F (200°C) for 8 to 10 minutes.

  4. Serve in the baking dish.

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

What each ingredient does

Cooked salmon
Forms the main body of the dish and provides its flaky texture.
Fish sauce or white sauce
Adds moisture and richness so the salmon does not dry out while baking.
Brown breadcrumbs
Form a crisp, golden top layer through browning in the oven.
Butter
Adds fat and richness and helps the breadcrumb topping brown.

The step that matters

Bake at 400°F (200°C) for 8 to 10 minutes. The dish is already cooked, so baking is mainly for heating through and browning the breadcrumbs. Too long can dry the salmon and sauce, while too short leaves the centre lukewarm and the topping pale.
