ML, N and T all loved this grilled flank steak last night and I made a promise to record the contents of my marinade, so here goes.
about (all measurements are approximate, as I didn't measure when I made it) 1/4 c Japanese soy sauce
2 tbsp Chinese cooking wine
1 tbsp black vinegar
1 tbsp honey
1 tbsp olive oil
2 cloves garlic, minced
2 green onions, minced
I cut the steak in 1/2 to 3/4 inch pieces on the bias (so the pieces had two thin edges) and marinated it in this mixture for about 4 hours in the refrigerator. I removed it, dried off the steaks and let them sit on the counter for about 1/2 hour. Grill over high heat.
