Flour tortilla by John Spottiswood.

These thin flour wraps from northern Mexico are used to make burritos, chimichangas, fajitas and other Mexican dishes. They're more pliable than corn tortillas, so they're a good choice if you need to roll or fold the tortillas before cooking them. Flour tortillas come in different sizes, including small, thick "fajita tortillas" to large, thin "burrito tortillas."
