Thanks for all the ideas.
I think one thing I'll do is grind my own some. I don't have a grinder, unless it's hidden around here somewhere. I think it may work in a food processor if I'm careful not to over process.
My wife keeps wanting me to add some oatmeal as a binder.
I've put bacon in there before and it was great. Just have not done it in awhile. I've used panchetta and boy that was good.
As far as kimchi goes, I ate a lot of it when I was in Korea. There are over 100 types of winter kimchi alone. Some of that stuff will smoke you big time.
I've made sausage burgers using sausage rather than beef and those were good. Problem there is the wife doesn't like pork that much...except the butt like I did today...and ribs of course.
My daughter gave me something from Williams-Sonoma that goes in ground beef that made a good burger.
I also think I over work the meat sometime in order to get it to stick together and not fall apart. Ain't sure why my hamburger making has gone down but I think y'all have helped me get it back on track.
Thanks, Dee
