Jim, barbacoa and lengua are always better when someone else makes it. Barbacoa is steamed, not BBQ'd but I guess you could try it. 1st time I had it in SA it was goat, which was pure heaven in a tortilla. Typically in Houston it's beef, just as good, super beefy. It's super fatty so I'd think twice about putting it over a fire, hate to see the Pigvillion in flames from an out of control grease fire. I tried making lengua, let's just say it's better when someone else makes it and leave it at that.
