Mix first 6 ingredients for marinade. Put flank steak in freezer bag, pour marinade over it, seal bag, and freeze. To prepare for serving, thaw flank steak, remove from marinade and barbque 8-10 minutes per side; or set oven control to broil. Broil steak 6 inches from heat until brow, turning once, about 6 minutes on one side and 4 minutes on the other. Cut steak across grain at slanted angle and thin slices.

for a couple of months. I have made it same day though, and just marinate it for a couple of hours in the fridge.
