Trim any excess fat off of the steak and then add it to the bag. Move it around to be sure it's well coated. Remove the air from the bag and seal it. Then place this bag into a second bag -- to ensure it doesn't leak. Marinate for about 24 hours in the refrigerator.
While the steak is grilling, pour saved marinade into a small saucepan. Place the saucepan over high heat, bring to a boil, and then reduce to low and simmer to reduce it by about ¼, 15 minutes or so. Season it generously to taste with salt, pepper and a bit more honey if necessary. (Here's How to Season to Taste.)
