Those of you who know what I'm talking about, and have had them, good tacos de cabeza, (beef head or tender goat head traditionally) or any other meat al vapor (steamed)pressure cooked. Any suggestions? Familiar with the tacohunt blog and others but no mention of tacos al vapor. With the vastness of taco truck heaven in L.A. there's gotta be some vendor who know's what they're doing, or are they just not around in L.A.? All help/suggestions appreciated.
