Even as traffic slithers to a crawl west of the 405 Freeway on Santa Monica Boulevard, drivers may be hard-pressed to notice the small storefront known as Naan Hut standing on their periphery. Neither its name nor its red-and-yellow signage offer any indication that a 1,000-year-old Persian tradition of baking naan sangak is upheld within these walls in the heart of Tehrangeles, the unofficial name for the West L.A. stomping grounds of L.A.’s Iranian diaspora. An ancient bread, legend ascribes the origins of sangak to the 10th-century Persian military. Soldiers would march together carrying small river stones known in Farsi as “sangak,” arranging them together at their day’s destination to aid in the special technique of baking this bread come chow time.
