Georgia, I can attest...
Tip's Rub is great on burgers, beef steaks, pork and chicken! also is great on sweet onion slices (marinated for 24 hours), then grilled...
I have used it on all now!
It's a unique flavor, and definately AWARD WINNING!
I have yet to try it on fish though! I think it would be really good on shrimps though...
