The folks at La Sonorense realize that a thick and chewy flour tortilla is a terrible thing, so they make their tortillas, available from 5-inch taco all the way to 15-inch burro size, into delicate paper-thin and par-cooked disks, selling them out by the two-dozen pack in their tiny, friendly cash-only shop on Central. The best thing about par-cooked tortillas? Getting the thrill of seeing a tortilla poof up into a perfect pillow without all that rolling and flour dust everywhere.
La Sonorense's primary business is to supply local restaurants, and chances are if you've had a fantastic flour tortilla anywhere in town, it is one of theirs. Their corn tortillas are equally delicious, but it's even better to pick up their tortilla masa, sold still warm by the pound, and try your hand at making them at home.
