Tiny little Pasadita might be the smallest restaurant in Dallas. Ana Ortiz makes papusas in a postage stamp kitchen in the back of a convenience store on Carroll Street. This might not be exceptional but for the fact that Ortiz's pupusas are the very best in Dallas. For evidence, look at her curtido first. The lightly fermented cabbage slaw has a little extra crunch, when compared with other pupuserías. Then taste the salsa, which is often plain and runny but here boasts crunchy onions, fresh cilantro and big-time heat. Finally, check out of the chicharrón. The rich, shredded pork packs a whole pig's worth of flavor into a morsel not much bigger than a marble. Now combine all of this evidence in one massive bite. The salty pork, the crunchy cabbage, the melting cheese and the bright and spicy salsa — if you're not careful, one of the neurons in your pleasure center could burst.
