NPR : Summer's Here: Grills Catch Fire: "Spice-Rubbed Flank Steak with Cajun Swamp Sauce

Hanger steak also is excellent prepared this way.

2 medium garlic cloves

1 1/2 teaspoons grated fresh ginger

1 teaspoon salt

1 teaspoon black mustard seeds (optional)

1 teaspoon ground cinnamon

1 teaspoon ground coriander

1/2 teaspoon black pepper, or to taste

1/2 teaspoon ground cumin

1/2 teaspoon cayenne (optional)

1 1/2 pounds flank steak, trimmed of excess fat

With a mortar and pestle, mash the garlic and ginger into a paste. (You can use a flat meat pounder or mince very well with a large chef's knife). Add the remaining seasonings. Salt to taste.

Pat the steaks dry with paper towels. Rub the paste all over. Cover in plastic wrap and marinate steak for about 5 hours or, better, overnight.

Oil the grill grates. When the grill is hot, cook the steak for 5 to 8 minutes on each side for medium-rare (depending on thickness). Test with a meat thermometer -- 145 rare, 160 medium. Transfer steak to a cutting board and let stand 10 minutes.

With a very sharp knife slice the steak thinly with the grain and serve."
