Tournedos Rossini

Instructions

1. 1
   Take the beef tenderloin medallions out of the refrigerator 30 minutes before cooking to remove the chill. Pat them perfectly moisture-free with paper towels and season robustly with salt and pepper.
2. 2
   Assemble the vegetable skewers by alternating the cherry tomatoes and zucchini barrels on wooden sticks. Sear them in a scorching hot grill pan with a drop of oil until nicely charred and tender as shown in `tournedos rossini.png`. Set aside warm.
3. 3
   Melt 20 grams of butter in a small skillet. Fry the round brioche slices until completely crisp and golden on both sides. Place them in the center of your wide, shallow white serving bowls as foundations.
4. 4
   In a heavy-bottomed skillet, bring the neutral oil to a screaming high heat. Sear the tournedos for 2-3 minutes per side, forming that uniform, caramelized deep-brown crust highlighted in the image. Keep the heat high to avoid boiling the meat. Rest the steaks on top of the fried bread.
5. 5
   Wipe the excess oil out of the hot skillet. Retrieve your foie gras slices directly from the fridge (they must be rock-firm and icy cold) and season them lightly.
6. 6
   Lay the foie gras into the dry, blazing hot pan. Sear for 30-40 seconds per side until a crisp golden coat develops while the inside stays velvety. Immediately place each piece over the resting beef steaks.
7. 7
   Pour off almost all of the rendered foie gras fat from the skillet, leaving just a thin coat. Splash in the Madeira wine to deglaze, vigorously lifting the rich, caramelized fond from the floor.
8. 8
   Let the wine simmer and reduce by half over medium-high heat, then pour in the concentrated beef demi-glace. Simmer for 3-4 minutes until the sauce coats the back of your spoon.
9. 9
   Kill the heat completely. Drop the remaining 20 grams of cold butter cubes into the pan, swirling continuously in a circular motion to emulsify the fats, creating that glossy, mirror-like finish from the photo.
10. 10
    Spoon the luxurious Madeira sauce smoothly and elegantly around the base of the bread and steak, creating a clean pool.
11. 11
    Top the seared foie gras with a few flakes of sea salt.
12. 12
    Gently nestle the colorful grilled vegetable skewer diagonally on the left flank of the plate and serve this historic culinary masterpiece immediately.
