It's tough to kill that flavor but I have had pretty good luck cutting the meat into thin strips and using my favorite marinade (my own salad dressing, honey, olive oil, apple cider vinegar, little catsup, Worchester sauce, crushed garlic) ... I put the strips into a container in the fridge with a lid the day before then barbeque... doesn’t take much time as the meat cooks to a certain extent from the vinegar... and of course I am very carful to cool the kill and not touch any meat with hands or equipment that has touched the hide... all the white (fat) is trimmed out...
I have never had to worry about that here as we hunt July/August for blacktail but I've shot a couple of muleys that needed help
The kids stand around the BBQ with their mouths open and eat it like candy..
