Tacos al Vapor
Tacos “al vapor” are a northern Mexican specialty featuring corn tortillas that are steamed instead of warmed on a griddle, giving them a slick, slippery outside with a texture similar to al dente pasta, albeit with the subtle fragrance and flavor of corn. Fillings tend to be on the moist and creamy side to work better with the tortillas. This truck only serves three types of tacos—beans (of the refried variety), boiled potatoes, and shredded beef. Such ingredients can easily turn out bland and mushy, but the ingredients here are well-seasoned, and a curtido-esque side of shredded cabbage can be piled on top to give the whole thing a pleasant crunch. Top everything off with a drizzle of the zingy, acidic tomatillo sauce and you may never go back to regular tacos again.
