Marinated Steak with Worcestershire Butter

Ingredients: Two pounds of steak tenderloin, One half cup of butter, Two teaspoons of coarsely ground pepper, Two garlic cloves, minced; One teaspoon of red pepper flakes, One cup of extra virgin olive oil, Two tablespoons of Worcestershire sauce, Six tablespoons of Dijon mustard, One tablespoon of pepper, Three tablespoons of light brown sugar and One quarter cup of soy sauce. 

Preparation: Make Worcestershire butter first by blending one half cup of softened butter, one tablespoon of pepper and two tablespoons of Worcestershire sauce. Reshape and cool so that butter can be sliced later.

Preparation (marinade): Combine Dijon mustard, soy sauce, fresh garlic, coarse ground pepper, red pepper flakes and brown sugar in a blender. With blender running, slowly drizzle in olive oil. Rub tenderloins with marinade. Place in a shallow dish and pour in any remaining marinade. Cover and let marinate for twelve to twenty four hours in the refrigerator for best results. Grill tenderloins on the coolest spot of a hot grill about ten to twelve minutes on each side until medium rare. When finished remove tenderloins from grill and let rest for about ten minutes. Serve with a slice of the Worcestershire butter on each piece of tenderloin, spreading lightly. Let butter melt and serve immediately.
