- 2 (1-inch-thick) sirloin tip steaks (2 lb total)
- 1 tablespoon vegetable oil
- 1/2 stick unsalted butter
- 3 1/2 tablespoons drained bottled horseradish
- 1 teaspoon Worcestershire sauce
- Pat steaks dry and season with salt and pepper. Heat oil in a well-seasoned large cast-iron skillet over moderately high heat until hot but not smoking, then cook steaks 6 minutes on each side for medium-rare. Transfer steaks to plates. Remove skillet from heat and immediately add butter and horseradish, stirring and scraping up any brown bits. Stir in Worcestershire sauce and spoon sauce over steaks.
