Made this recipe today, and it was grand. Of course, I adjusted it a bit. Cut the salt, added a bit of cumin, varied a few ingredients I didn't have. I used pork tenderloins, and it worked great. Even went to the Kensington Market and got fresh tortillas.
I grilled rather than smoked. 2 hours at 250, then charring for about 15 minutes. Lots of gobbling and compliments. Thanks to all.
