For Steak:
Drizzle steaks with EVOO, season with salt and dredge all sides of the steaks in the peppercorns. Heat 2 tablespoons EVOO in a cast-iron skillet over high heat. Once skillet is hot, add 2 tablespoons butter and steaks, and brown on all sides Once steaks are cooked to desired doneness, remove from the pan and set aside to rest. Put the pan back on the stove over medium heat (with all the good steaky bits and things left in the pan). Deglaze pan with cognac then add the stock and reduce until thick enough to coat a spoon. Whisk in remaining butter and season with salt and pepper. Pour pan gravy over the steaks, serve, eat and be happy.
