In a bowl whisk all ingredients together. Put 2 lbs. of steaks in a large freezer bag. Pour sauce on top. Eliminate air in bag and seal shut.
Rotate meat so it is coated. Lay flat in fridge for at least 2 hours, or longer.
Remove, discard marinade in bag and cook steaks as desired.
If you wanted to make this into a sauce too you could make a second batch and cook on the stovetop. When bubbling whisk 1 tbsp cornstarch in a small dish with some of your liquid until smooth. Whisk into saucepan to thicken, then allow to cool.
