BBQ Steak Marinade

This is a quick marinade using Asian ingredients for beef steaks (like tri tip cut).

Combine following for marinade (will coat around 1 LB of meat):
1 TB Sake
1/4 C Soy Sauce
1 TB brown sugar
1 tea sesame oil
1 tea white miso
1 tea dark "hatcho" miso
1 TB white vinegar or Japanese komezu (rice wine vinegar)
optional: grated ginger

Toss with meat, tenderize with a fork, and let sit in refrigerator for 15 minutes.

Grill on hot BBQ and serve with 15 minute rustic mashed potatoes.
