Spicy grilled steak (shawayuh)

2 lb Beef boneless sirloin steak
           - (1 1/2-inches thick)
  1 1/2 ts Coarsely ground pepper
    3/4 ts Caraway seeds
    3/4 ts Ground turmeric
    1/4 ts Cardamom seeds, crushed
 
  Slash outer edge of fat on beef steak diagonally at 1-inch intervals to
  prevent curling (do not cut into lean). Mix together remaining ingredients.
  Sprinkle on both sides of beef and lightly press into beef. Cover and
  refrigerate at least 1 hour. Grill beef 4 to 5 inches from medium hot
  coals, turning 2 or 3 times, until of desired doneness, 25 to 35 minutes
  for medium. Cut into serving pieces.
