Terry,
That is a great steak rub and it did finish 3rd in our steak rub trials. We didn't try it on anything but steaks and I felt that it might be improved with a little more heat but my bride said it was fine the way it was.
I would offer a suggestion to give it more time for the rub to work after it is applied to the steak. I also think is is best to place the steak on a raised cooling grid of some type to allow the air to get under the steak during this period.
This is what we use in our rub trials.
I found that it was best to allow 40 minutes warm-up with the rub to be sure we could get the steaks to the sweat stage and then have time for some of the spices to be absorbed back into the meat.
Anyway, that is what worked for us with this rub.
Dave
