Just come back to Saigon after a few days in the Mekong Delta. Above's a snap of small noodle factory I poked my snout into down there....
Looks like they're making rice papers at first glance but it's actually noodles. Not the fresh no-need-to-cook type you eat so often in Vietnam (which are made from cooked rice), this method uses raw broken rice grains and produces a large rice paper sort o thing.
These they dry in the sun for few hours, before running them through a big pasta cutter type machine.
Out come fine dry-ish noodles, which are bagged up and driven to market on the back of a motorbike (this being the only option, as there's just a dust track leading out from the place).
The whole operation was v.rustic - mud floor, chickens clucking around etc, but all pretty skillful and efficient too. Just like so many things in Asia.
