That's looks amazing! Quite fitting for the topic of this thread, "time to hype up some bear hunters". If that picture doesn't do it, I don't know what will
I would really like to try doing something more with bear meat (other than ground) one of these days. Smoking isn't currently an option.
I do think I know what you mean by "stringy" with regard to ground. Sometimes I find it to have a more fibrous or even grainy texture compared to beef, but not always. I was never really sure what to attribute that to (ie: cooking, bits of silverskin, or it's just how the meat is) ... I did find the more picky I am about trimming and what goes in the grinder, the better the texture is. Could be all in my head though.
