I got a sample of Tatonka Dust with my Vortex. I used it and the wife and I loved it. I had used about one third of the bottle. I went to use it again a couple of weeks later and it had set up like concrete. I couldn't chip it with a knife to break it up so I could use it. I had to throw it away.
After I got my Vortex I told a buddy in Texas about it and he ordered one, as well. And, he got the Tatonka Dust with it. He used it on wings and really liked it. I was talking to him the other day and we were talking grilling and I mentioned the Tatonka had hardened. He sent me a message later and said the same thing had happened to his and he had to toss it out.
I stored mine a cabinet with all my other spices and rubs and none of the others have done this. I know it didn't get wet. Has anyone else had this experience? I really like the stuff and want to buy some more but not if I can't use it.
