Why your favorite stir-fry noodles might actually be two different culinary traditions

In short: While often used interchangeably in casual restaurants, shahe fen and kway teow are distinct rice-based noodles with different origins and textures. One is a porous Cantonese creation designed to soak up savory sauces, while the other is a denser, starch-heavy descendant of ancient rice cake preservation techniques.

Shahe fen originated in the town of Shahe, now part of Guangzhou’s Tianhe District in Guangdong province. These white, broad, and slippery noodles are prized for their elastic, chewy texture. Because they do not freeze or dry well, they are typically purchased fresh in sheets or strips. Cantonese cooks developed these noodles to be thin and tape-like, featuring porous areas that effectively absorb the flavors of the broths and sauces in which they are stir-fried, a dish commonly known as chao fen or chow fun.

In contrast, guotiao, or kway teow, has roots in Northeast China and stems from an ancient method of preserving rice as a dense, starch-filled cake patty. This version is significantly less absorbent than shahe fen. Because of its density and higher starch content, authentic kway teow is stiffer and often requires soaking for a day or more before cooking to achieve the desired texture. While Cantonese culture became highly influential from the 17th century onwards, leading some to modify the traditional guotiao process to mimic the popular shahe fen, many Minnan speakers still maintain a strict distinction between the two.

These noodles have spread across Asia under various names, including sen yai in Thailand, hủ tiếu in Vietnam, and pan-tiau among the Hakka. While they are often grouped together, the difference in their production—specifically the removal of starch in shahe fen versus the preservation of it in guotiao—creates a unique culinary experience. Whether you are eating a stir-fry in Singapore or a soup in Vietnam, understanding the history of these rice strips reveals a complex map of regional migration and cultural adaptation that continues to shape modern Chinese and Southeast Asian cuisine.
