Cold Fish Au Gratin

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.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. If you have fish sauce, warm it; if not, make a sauce with milk or water, butter, and flour.

  3. Flake the fish into pieces.

Assemble and bake

  1. Butter a plate and place the flaked fish on it.

  2. Pour the sauce over the fish.

  3. Sprinkle with brown bread crumbs.

  4. Bake in the oven for 15 minutes.
