The recipe

Oven, in the book's wordsA brisk oven

Ingredients

Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

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

  1. Sauté the tournedos until underdone.

  2. Fry the thin slices of bread in butter until golden.

  3. Place each tournedos on a slice of fried bread.

  4. Top each tournedos with a slice of fat goose liver.

  5. Pour Mornay sauce blended with one-third part Soubise sauce over the tournedos.

  6. Sprinkle grated cheese and bread crumbs on top.

  7. Drizzle a few drops of melted butter over the dish.

  8. Bake in a brisk oven at 400°F (200°C) until golden.
