A friend uses Claude's Marinade in his Jerky. I've used it on Brisket. I prefer Gold Buckle Brisket & Fajita marinade.
If you really like Claude's - Double D Meats in Mountlake Terrace, WA stocks it.
Claudes is a little too salty for me but... Uncle Chris' gets used alot around my house. I go through at least 4 or more a year.
That's awesome that your friend was thoughtful enough to send you some new things from her region. The Uncle Chris' is great on burgers too.
That's how some of us find new things that are really good, friends will always share good things with each other.
