Willy-
The Baron's book is all seasoning recipes, simple to complex. He walks you through the process. I actually found his on a close-out rack for $2.95. I wish I'd bought the whole stack. No food involved, just ingrediants to make rubs etc. The BBQ sauce we bottle and sell was derived by reading his book.
Smoke & Spice takes food and doctors it up to make a complete dish { I hope this make sense }. One of our signiture dishes, with a few modifications, are the smoked olives on page 267.
Comparing the two in my opinion is apple/oranges.
I now order books over the phone from Barnes and Noble which we have locally. If you don't like the book you can return it {which is what I did with Kirk's most recent book}.
Of course now that I've discovered this forum, how needs a cookbook?
Good Luck! Roger
