Beef Tenderloin With Black Truffle Sauce

• For the Truffle Sauce
• 4 cups chicken stock (preferably homemade)
• 1/2 cup medium dry sherry
• 1 seven-ounce can black truffle peelings
• 1 tablespoon butter
• 1 pinch salt
• For the Beef Tenderloin
• 1 Cleaned beef tenderloin, about 7 or 8 inches long
• 1 pinch salt
• 1 splash canola oil
• 1 handful thinly sliced chives, for garnish (optional)

1. Set a large pot over high heat and add the chicken stock. When the stock has reduced to about 1 cup of total liquid, reduce the heat to medium and add the sherry along with the the can of truffle peelings (the truffles and all of the accompanying truffle juice). Let the liquid in the pot reduce until the liquid appears less watery and slightly sticky. The difference will be subtle. When you are happy with the consistency and texture of your sauce, remove it from the heat.
2. Preheat the oven to 375. Season the beef tenderloin liberally with salt all over. Set a large skillet over high heat and add enough canola oil to just barely cover the skillet in oil. When faint wisps of smoke just begin to appear, add the beef to the skillet. Sear the beef on all sides, so that the exterior looks brown and caramelized. Next, transfer the beef to the oven. After 10 minutes in the oven, use a digital thermometer to check the temperature of the beef. For pink steak, remove the beef from the oven when the thermometer is inserted into the center of the tenderloin and reads 130 degrees. Keep checking every 5 minutes or so until you have reached the desired temperature. When you are happy with the temperature of the beef, remove it from the oven and let it rest for 10 minutes before slicing it.
3. While the beef rests, finish the sauce. Set the pot of sauce over low heat, and add the butter. Stir gently to incorporate the butter into the sauce. Taste the sauce and add salt as necessary. When your sauce is perfect, slice the beef tenderloin into medallions that are 1 inch thick. Spoon some sauce onto a plate, add a few slices of beef, and top with more sauce. Garnish with chives. Serve and enjoy.
