The puffy taco was invented by accident in 1950s San Antonio when a cook dropped raw masa dough straight into hot oil instead of pre-baking it.
Fresh masa dough is deep-fried to order, puffing into a crisp, air-pocketed shell that's folded around ground beef or chicken, lettuce, tomato, and cheese while still hot. It's a San Antonio specialty rarely found outside the city.
