It's a pre-mix of assorted spices. I just buy it in the grocery store along with all the other spices in bottles. Or at the bulk store.
I just checked with MrGoogle and he has lots of recipes to make your own ... each one seems to have a different combo though! And I have no clue what combo is the one I purchase!!! :) I find it's just an easy way to add spice, all in one bottle ... and not be dragging out a bunch. Wouldn't do it!! :)
