Ingredients for the Known Ground reconstruction

Ingredient amounts shown for 2 servings.

Known Ground reconstruction

  • 1whole partridge, patted dry
  • 3 tbspunsalted butter, divided
  • 1 ozfresh black truffle, thinly sliced
  • 1/2 cupthick béchamel, Soubise
  • 2 tbspheavy cream, Soubise
  • 1/4 tspsugar, Soubise
  • kosher salt, to taste

Soubise

  • 1 lbyellow onions, thinly sliced

Known Ground reconstruction

The accompanying sauce is reconstructed from no. 104 instead of using a generic onion purée. Its thick, smooth consistency is intentional. This version has not been personally tested by Known Ground. Cook the bird and any poultry forcemeat to 165°F (74°C) in its thickest portion.

Instructions

1. Blanch the onions for 3 minutes, drain and dry them, then stew gently in 1 tablespoon butter. Add béchamel, sugar, and salt; cover and cook for 30 minutes.

2. Blend the onion mixture until completely smooth, then finish it with cream and 1 tablespoon butter. Keep the Soubise hot without boiling.

3. Season the partridge and cook it gently in the remaining butter in a covered casserole, turning to colour evenly, until it reaches 165°F (74°C).

4. Set the partridge on a warm platter, surround it with the truffle slices, and serve the Soubise separately.
