Blackened Flank Steak - cooking recipe

Ingredients

1 or 2 flank steaks (1 to 1 1/2 lb. each)
1 1/2 tsp. salt
1 1/2 tsp. white pepper
1 1/2 tsp. whole black peppercorn
1 1/2 tsp. fennel seed
2 1/2 tsp. cayenne pepper
2 1/2 tsp. dry mustard
2 Tbsp. garlic powder

Preparation

Grind all ingredients except steak in food processor or blender.
Coat both sides of flank steak with dry mixture.
(If cooking only 1 steak, use half the mixture and save the rest for future use.)
Coat a seasoned cast-iron skillet with olive oil; heat until smoking (you may want to do on an outside grill, due to smoke alarm).
Sear steak on both sides; meat will be black.
For rare, cook 5 minutes on each side.
For medium, cook 7 minutes on each side.
Slice diagonally in thin strips.
