Luosifen

What is Luosifen?

Luosifen is a noodle soup centered on rice vermicelli, served in a broth steeped with river snails and bones, then layered with a variety of toppings. The soup is seasoned with a mix of spices and herbs, while the toppings often include pickled bamboo shoots, peanuts, tofu skin, and chili oil. The pickled bamboo shoots give the dish its distinctive, sometimes divisive, smell. Other additions might be wood ear fungus, green beans, or leafy greens. The noodles themselves are made from aged rice, giving them a firm bite. The overall flavor is complex, spicy, and sour, with a strong aroma from the fermented bamboo.

Where does Luosifen come from?

Luosifen began in Liuzhou, Guangxi, sometime in the late 20th century, when cooks combined two local favorites: snail soup and rice noodles. Its rise as a street food followed economic changes in the city, with many new stalls opening in the 1990s. The dish gained national attention after appearing in a food documentary in 2012, and soon after, the city promoted it as a local specialty. By 2014, instant versions were being produced, and luosifen became widely available across China and online.

How is Luosifen made?

To prepare luosifen, cooks simmer river snails and bones for many hours with a blend of spices and herbs to create a rich, aromatic broth. The rice noodles, made from aged rice, are soaked and cooked separately. Toppings like pickled bamboo shoots, peanuts, tofu skin, and vegetables are prepared in advance. The noodles are placed in a bowl, covered with hot broth, and finished with the chosen garnishes. Instant luosifen comes with separate packets for broth, noodles, and toppings, ready to be assembled after boiling water.

How and when is Luosifen eaten?

Luosifen is usually eaten as a main meal, either for lunch or dinner. It is most often enjoyed in restaurants, noodle shops, or street stalls, where diners can select their preferred toppings. At home, people often prepare instant versions. The dish is rarely made from scratch in home kitchens due to the lengthy process. It is typically served hot, with side dishes like marinated eggs or duck feet sometimes offered. The strong smell is part of the experience, and many consider the pickled bamboo shoots essential.

Kinds of Luosifen

While the classic luosifen uses rice noodles, snail broth, and pickled bamboo, many versions exist. Some shops add extra proteins like pork, duck feet, or even seafood. Toppings can vary by season or region, with vegetables like water spinach in summer and lettuce or mushrooms in winter. Instant luosifen is popular and comes in many flavors, adjusting spice levels or adding different garnishes. Outside China, similar dishes appear, such as the Vietnamese bún ốc, which also uses snails and noodles.

What Luosifen means

Luosifen is closely tied to Liuzhou's identity and has become a symbol of the city. Its popularity soared after being featured on television and through the growth of instant noodle sales, especially during the COVID-19 pandemic. The city has invested in luosifen production, opening an industrial park and even a vocational school focused on the dish. Its strong smell and unique taste have sparked debate, but also contributed to its fame as a distinctive regional food.
