Beef Tenderloin with Yukon Gold Potatoes, Chili-Cured Onions, and Horseradish

The contrast of textures and flavors - crunchy onions, seared steak, creamy horseradish - in this dish from Tobias Lawry of Ajax Tavern in Aspen, Colorado, is phenomenal. Any potatoes will work in place of the Yukon golds.
