Snail Noodles (螺蛳粉): Luosifen Explained

Luosifen — the fermented-smelling rice noodle dish from Liuzhou, Guangxi — became one of China's most talked-about foods in the 2020s. Here is what it is, why it smells the way it does, and how to eat it properly.

Luosifen (螺蛳粉, river snail rice noodle) is from Liuzhou, Guangxi. It consists of round rice noodles in a river snail broth base, topped with pickled bamboo shoots (the source of the distinctive smell), dried tofu skin, peanuts, wood ear mushrooms, and adjustable chilli oil.

The smell comes almost entirely from the pickled bamboo shoots — not the snails. Most people find the taste milder than the aroma suggests: the bamboo shoots deliver sourness and umami; the broth is meaty and slightly sweet.

During 2020 lockdowns, luosifen instant noodle packets became China's most discussed snack food. In 2021, Liuzhou reportedly shipped over 1.5 billion packets generating revenues of over 10 billion yuan. The product now has GI certification for Liuzhou-produced versions.

In Liuzhou, a bowl costs ¥10–20. Order by heat level: 微辣 (slightly spicy), 中辣 (medium), 重辣 (very spicy). Add extra pickled bamboo shoots if you've accepted the flavour profile.
