Trim all fat from flank steak

In a large pan, put 4 cups Cold water and the baking soda and stir to dissolve the baking soda

Place the flank steak in the pan and soak for 10 minutes. Remove the steak from the water and dry very well with paper towels

In a bowl large enough to hold the steak, mix the Bourbon, sugar, garlic, hoisin sauce, and vegetable oil very well and dip both sides of the steak in the mixture. Marinate on a plate for 2 to 3 hours or longer in the refrigerator

Heat the broiler or grill

For medium, broil 4-5 minutes on each side, or until browned. If you want well done, cook for 2 minutes longer. Grill for 8-10 mins per side for medium.

Remove from broiler and let stand for 2 minutes. Slice across the grain into 1 quarter inch slices for serving
