A puffy taco is not a crispy taco, a crunchy taco, or a soft taco. It is strictly a puffy taco, and after having one (or three), you may be willing to forsake all other taco forms. Chef Diana Barrios-Treviño Los Barrios in San Antonio will readily admit that she didn't invent the puffy, but she and her family have perfected them over the years. Maybe you've seen her make them on Throwdown with Bobby Flay (and win)? The puffy taco shells are super-crisp on the outside but soft within—surprisingly light for fried dough. We were recently in San Antonio and learned how to make the Tex-Mex specialty.
