The noodles are made from mung bean starch rather than rice or wheat, which is why they turn glassy and almost transparent instead of opaque white once cooked.
Glass noodles are simmered in a light chicken broth with wood-ear mushrooms and shredded chicken, finished with fried garlic, coriander and a squeeze of lime. Mandalay's soup stalls serve it as a lighter counterpart to the city's richer noodle dishes.
