Grilled Spiced Flank Steak

    3/4 teaspoon cinnamon
    3/4 teaspoon ground coriander seeds
    3/4 teaspoon ground cumin
    3/4 teaspoon black pepper
    1 teaspoon salt
    a 1-pound piece trimmed flanked steak

  In a small bowl stir together spices and salt and rub on both sides
 of steak. In a large sealable plastic bag marinate steak, chilled,
 at least one hour. Steak may be marinated, chilled, overnight.

  Prepare grill. Grill steak on an oiled rack set 5 to 6 inches over
 glowing coals 5 minutes on each side for medium-rare meat.
 (Alternatively, steak may be grilled in a well seasoned ridged grill
 pan over moderately high heat.) Transfer steak to a cutting board and
 let stand 10 minutes. Holding a sharp knife at a 45 degree angle, cut
 steak across grain into very thin slices.
