Reshteh (Persian: ????), from the Persian word for thread or string, refers to a very fine noodle similar to capellini (angel hair pasta). However, it generally means a fresh (as opposed to dry) ribbon shaped egg noodle. Traditionally the noodle would be a homemade and cut item. Reshteh was the only word used to denote noodles in Arab cookbooks of the 13th and 14th centuries. Special symbolism is given to dishes that contain noodles when a decision of importance or change is to occur; the noodles or "reins" of one's life are to be taken in hand. A traditional dish in Iran is reshteh polow or pilaf, which is served during the Persian new year with the noodles representing the threads of life and family intertwined. Noodles, though common in the Arab world, are used for special occasion dishes in giving thanks and for journeys especially to Mecca. Typical preparation is for the noodles to broken into parts, fried or grilled brown and then added to rice.
The reshteh used currently in the Iranian cuisine is actually a thicker type of noodle, used in reshteh polow and also a type of ash, called Ash Reshteh
