  • One 1/2 to 2 pound steak (shell, flank and sirloin all work well for this recipe)

  • 4 cloves garlic, peeled and smashed

  • Fresh ground pepper


  1. Combine buttermilk, garlic and rosemary. Grind in a generous amount of pepper. Pour into a zippered plastic bag.

  4. Transfer steak to cutting board, cover with foil and let rest for 5 minutes before slicing and serving.
