The flour tortillas at La Sonorense Tortilla Factory in south-central Phoenix are fashioned out of four basic ingredients: flour, shortening, salt, and water. They are pressed into thin, par-cooked disks, which means they puff up enticingly when you warm them up over fire. Thin and pliable, La Sonorense's tortillas have the kind of richly buttery profile that makes them good enough to eat all on their own. Not surprisingly, many metro Phoenix restaurants and food trucks source their tortillas from La Sonorense. You can enjoy these terrific tortillas anytime by dropping into the factory's storefront on Central Avenue and grabbing a dozen (or two).
