• •Small saucepan

Instructions

1. 1

   Stage every component

   Take the tournedos from the cold about 25 minutes before cooking, leaving their strings in place so they hold a compact round shape. Heat the oven to 200°F (95°C) for the platter and croûtes. Cut the bread to match the diameter of the beef, keep the truffle wrapped until assembly, and place every measured ingredient beside the stove. Once the beef starts cooking, nothing else should demand your attention.

   Do not salt the beef yet. Season immediately before searing so moisture does not collect on the surface while the garnishes are prepared.
2. 2

   Braise the lettuces

   Arrange the lettuce quarters snugly in a wide sauté pan, cut sides down. Add 1¼ cups (300 ml) of the stock, 2 tablespoons (30 ml / 28 g) of the unsalted butter, and ¼ teaspoon (1.25 ml / 1.5 g) of the salt. Bring the liquid to a bare simmer, cover closely, and braise for 12 to 15 minutes, turning the quarters once, until a knife enters each firm root end without resistance but the leaves still hold together. Lift the lettuce into a shallow dish. Boil the braising liquid until about ¼ cup (60 ml) remains and looks glossy, then return the lettuce and turn it gently in the reduction. If the lettuce becomes tender before the liquid reduces, remove it at once and reduce the liquid alone. Ça se rattrape; stirring soft lettuce in a boiling pan does not.

   Leave enough of each root attached to hold the quarter together. A completely removed root gives you loose leaves rather than a composed garnish.

   Fry the croûtes

   Heat 3 tablespoons (45 ml / 42 g) of the clarified butter in the heavy skillet over medium heat. Fry the bread rounds for 2 to 3 minutes on each side, adding another spoonful of clarified butter only if the pan becomes dry, until both faces are evenly deep gold and the edges are crisp. Transfer them to a wire rack and hold them in the low oven. Do not place them on paper, which traps butter underneath and softens the crust. If the butter develops bitter black specks, discard it, wipe the skillet, and continue with clean clarified butter.

   The croûte must support the tournedos without collapsing into grease. Medium heat gives the bread time to crisp through before its surface becomes too dark.

   Prepare the kidneys

   If the cock's kidneys are raw, combine the remaining ¼ cup (60 ml) stock and the water in a small saucepan and bring them to the gentlest simmer. Add the kidneys and poach for 4 to 6 minutes, turning once, until firm, opaque through the center, and cooked to 165°F (74°C). Drain and dry them carefully. Heat 1 tablespoon (15 ml / 14 g) clarified butter in a small pan and color the kidneys lightly for about 1 minute, then season with a pinch of salt and hold them warm. If they were supplied already cooked, omit the poaching and warm them briefly in the butter. Do not chase a dark crust; these small organs toughen quickly.

   Ask the poultry supplier whether the kidneys arrive raw or cooked. Treating an already cooked product as raw will make it rubbery.
5. 5

   Ready the platter

   Warm a round serving platter for 5 minutes, then remove it from the oven and arrange the four croûtes in a close ring. Return the lettuce to the lowest heat so its glaze loosens without boiling. Set the kidneys and truffle slices beside the platter. This pause is the home kitchen's replacement for a brigade: every component is ready, and the beef can now receive your full attention.

6. 6

   Sear the tournedos

   Season the tournedos all over with the remaining salt and pepper. Wipe the heavy skillet clean, add 2 tablespoons (30 ml / 28 g) clarified butter, and heat it until the surface shimmers. Set in the beef with room between the pieces and sear without moving for about 2½ minutes. Turn and sear the second face for 2 minutes, then briefly color the edges. Add 2 tablespoons (30 ml / 28 g) unsalted butter, let it foam, and baste the tournedos continuously until they reach 125°F (52°C) for a rosy medium-rare finish after resting. For conservative food-safety guidance, cook whole beef to 145°F (63°C) and rest it for at least 3 minutes. If the butter turns black before the beef is ready, move the tournedos to a clean hot pan with fresh butter immediately; bitter butter cannot be hidden.

   Use temperature, not bravado. Tenderloin has little internal fat, and the difference between rosy and dry is only a few minutes.
7. 7

   Rest and rewarm

   Transfer the tournedos to a rack and rest them loosely covered for 5 minutes. Cut away the strings. While they rest, warm the lettuce gently in its reduced glaze and turn the cock's kidneys once more in their butter. Melt the final tablespoon (15 ml / 14 g) unsalted butter off the heat and brush it lightly over the rested beef. Keep the truffle slices at room temperature; the warmth of the tournedos will release their aroma without cooking it away.

8. 8

   Build the crown

   Set one tournedos on each fried croûte, preserving the ring on the platter. Overlap four truffle slices on each tournedos to form a small crown, then place one warm cock's kidney in its center. Arrange the braised lettuce quarters around the outside, cut sides visible, and spoon their reduced glaze over the lettuce without flooding the crisp bread. Carry the platter straight to the table. À table!

Chef Tips

• •Ask the butcher for evenly cut center portions of tenderloin, not thin tail pieces, and have each tournedos tied. Equal thickness matters more than exact weight because all four must finish together.
• •Cock's kidney is the traditional English name for rognon de coq, the rooster's testicle. Order it from a specialist poultry or offal supplier. If it cannot be sourced, four button-sized pieces of prepared veal sweetbread are the closest practical stand-in, but the garnish has changed and should be described honestly.
• •A whole preserved black truffle is the proper classical pantry answer when fresh truffle is not in season. Pat it dry and slice it thinly. Truffle-flavored oil cannot form the crown, and its perfume does not behave like the ingredient itself.
• •Clarified butter is still butter, with the scorch-prone milk solids removed. It lets the croûtes crisp and the beef sear at the heat this dish requires. Whole butter returns for basting and glazing. We don't apologize for butter.
• •Serve a supple red Bordeaux or an earthy red Burgundy with enough freshness to meet the truffle and braised lettuce. Avoid a heavily oaked, high-alcohol bottle that flattens the delicate tenderloin.
• •Tournedos Judic is best eaten as soon as it is assembled. If leftovers remain, remove the beef and lettuce from the croûtes before chilling them in separate covered containers for up to 2 days; the bread cannot be rescued once it has soaked.

Advance Preparation

• •The lettuces may be braised up to 6 hours ahead. Cool them promptly in their reduced glaze, cover and refrigerate, then rewarm over the lowest heat while the beef rests.
• •Raw cock's kidneys may be cleaned and poached a day ahead, then cooled promptly and refrigerated. Sear them lightly in butter just before assembly.
• •The bread rounds can be cut earlier in the day. Fry them within an hour of serving, or re-crisp them for 5 minutes in a 325°F (165°C) oven.
• •The clarified butter can be prepared several days ahead and kept covered in the refrigerator. Slice the truffle only shortly before serving so its aroma stays in the dish rather than on the cutting board.
