RE: What's the best way to prepare the tenderloins?
The best way I have found for any deer meat is:
-slice into steaks, I like mine thick
-marinade over night in 1 cup italian dressing (thick), Half cup hickory BBQ sauce, and 1/4 cup soy sauce.
-Grill over masquite wood until it is pink inside.
-Eat.
Its great. I have to admit I got this reciepe from the cooking board at this sight. I just had some deer steaks done like this last night, I can still taste them.
