'Smelly' noodles now come in a package

Yuan Xiang is ordering instant luosifen - a specialty of Liuzhou, Guangxi Zhuang autonomous region - online with friends in Shanghai.

"It's the third order we've placed this month," she said. "It might seem smelly to someone tasting it for the first time, but it tastes really good once you eat more."

Luosifen, which is made of rice noodles boiled and served in soup flavored with river snails and pork bones, is usually sold at roadside stands or night fairs in Liuzhou.
