I tried this once -- it was very salty, which I don't mind, but it was nothing special as far as tenderness.
This method works: Preheat grill to 500 deg F. Lightly salt and pepper the steak just before grilling. Grill for 4 minutes per side per inch of thickness. Remove, call the guests in, and serve. Yum.
Remove, [let rest for 5 minutes], call the guests in...
