Gustavo Arellano celebrates the Americanization of Mexican food:
Tortillas and tamales have long left behind the moorings of immigrant culture and fully infiltrated every level of the American food pyramid, from state dinners at the White House to your local 7-Eleven. Decades’ worth of attempted restrictions by governments, academics, and other self-appointed custodians of purity have only made the strain stronger and more resilient. The result is a market-driven mongrel cuisine every bit as delicious and all-American as the German classics we appropriated from Frankfurt and Hamburg.
