We know we've come home to Mexico when we catch that first whiff of smoky barbacoa wafting on the breeze. Whether it's from chicken, beef, pork, lamb or baby goat being grilled over an open mesquite fire or slow-roasted on hot coals in an open pit, that heavenly smell is, for us, an unmatchable part of the best of Mexican culture and cuisine. Carnicería El Camino keeps those fragrant home fires burning bright for homesick Phoenician Mexicophiles with its extensive selection of Mexican-style cuts of meat, poultry and seafood. A small, corner grocery store with a down-home, old-fashioned feel, El Camino is piled to the rafters with all ingredients Mexican, but it's the butcher counter that shines like the blazing sun over the ancient pyramids of Teotihuacán. Here you'll have no trouble finding real Mexican chorizo, diesmillo (thinly sliced chuck roast), cecina (paper-thin pieces of dried or partially dried and seasoned beef or pork), chuleta (huge, thin slices of pork or lamb both unsmoked and smoked) or carne de chivo and borrego (goat and sheep, respectively) for barbecuing. The store also has 100 percent Mexican brand Chimex salchichón (a spicy, salami-like sausage), beef tongue, premade fajita mix for the less ambitious of us cooks, and codornices (quail). If you're a seafood lover, El Camino has that covered, too, offering large uncooked shrimp, pulpo (octopus), and, on the weekends, fresh ceviche. Also available for those weekend hangovers is classico rico menudo, a sloshy, tongue-searing tribute to beef tripe, hominy and calf's knuckles that's a guaranteed cure for those who have over-partied on the fin de semana.
