02Preheat the oven to 375 degrees F.03Set a large cast-iron pan (or roaster) over high heat and coat lightly with canola oil. Remove the beef from the fridge and discard the plastic. Place the roast seam-side down in the pan and brown on all four sides, 4 to 5 minutes per side. When completely browned, place the whole pan in the oven and roast for about 30 minutes (an instant-read thermometer should register 135 degrees F for medium-rare). When done, remove from the oven and transfer the roast to a platter to rest before slicing into 1/2-inch-thick slices.04For the peppercorn sauce: Set the pan used for the beef over medium heat. Discard all but 2 to 3 tablespoons of fat from the pan, and then add the garlic and shallots. Season with some salt and saute until caramelized, 2 to 3 minutes. Then add the green peppercorns. Mix well, and then remove the pan from the heat and carefully add the whiskey (you can flambe if you like here by igniting the alcohol in the pan). Return the pan to the heat and cook down until just about all the liquid has reduced before adding the beef stock and heavy cream. Bring to a simmer and cook to allow flavors to meld, 2 to 3 minutes. Remove from the heat and add the cold butter cubes, swirling as they dissolve. Taste and, if needed, season with more salt. Serve with the slices of bacon wrapped tenderloin.
