Sweet Water Noodles

01

Thick noodles in sweet soy and chili oil

Sweet water noodles are thick, chewy noodles in a dressing that is sweet first and hot second.

More than a century ago a Chengdu writer complained that sweet water noodles were too thick. The thickness is now the point. The noodles are a little thicker than chopsticks, springy and very chewy, and locals joke that “three noodles make a bowl,” 三根面一碗. Fuchsia Dunlop calls them a snack every Chengdu person loves: hand-cut noodles in glossy chili oil and sweet soy, scattered with crushed nuts and garlic.

The second thing you notice is the sweetness, which a Chengdu breakfast roundup from Hong Kong’s Chinese Culture Research Institute calls the key to the dish. The “sweet water” is simply a soy sauce simmered with sugar and spices. Chili oil and garlic come in behind it, and many cooks add sesame paste and crushed peanuts. The noodles are cooked ahead, tossed with oil and served at room temperature; dressed this way they keep for hours without drying out, which suits a snack sold from early morning. Before eating, turn the bowl over from the bottom so every strand is coated in the thick sauce.

Rolled, cut, stretched and slapped

Many Chengdu noodle shops buy their noodles. Sweet water noodles are made in the shop.

Most Chengdu noodle shops, Dunlop notes, buy fresh noodles from a supplier. A few kinds are made in house, and sweet water noodles are one of them: thick, and cut straight from the dough. In the kitchen of Dongzikou Zhang Lao’er Liangfen, the old snack shop opposite Wenshu Monastery, she watched a cook named Jiang knead the dough by hand and roll it out on a wooden table with a long rolling pin. He cut it into thick strips, picked up a few at a time, stretched them, slapped them on the table and dropped them into a big pot of water.

It is a plain, non-alkaline wheat dough, made with the same flour used for steamed buns. Chinese Cooking Demystified class the noodle as gungunmian, “stick noodles,” a thick style better known in neighboring Shaanxi, and compare it to Japanese udon. Because the noodles are meant to be chunky, there is no need to cut them perfectly. For a chewier noodle, use high-gluten flour and flatten and fold the dough several times as it rests.

The “sweet water”: sweet aromatic soy sauce

The sweetness comes from a Sichuan pantry staple, 复制酱油, “reprocessed soy sauce.”

Sichuan cooks make their own sweet soy sauce, also called red soy sauce, 红酱油, by simmering soy sauce with spices and sugar until it is sweet, fragrant and as thick as syrup. Dunlop counts it among the marvels of the Sichuan kitchen: it is essential for Zhong dumplings and sweet water noodles, and it goes into cold dishes too. There is no fixed formula. Each cook has preferences, some simmer dried shiitake stems in it for extra savoriness, and the usual spices include star anise, cassia, licorice, fennel and Sichuan pepper, cooked long enough to turn a glossy reddish brown, salty with a sweet edge.

The two recipes in the table show how far the sweetness can vary. Dunlop’s sauce has 275 g of sugar to 500 ml of soy, roughly half as much sugar as soy, and eight spices; Chinese Cooking Demystified use sugar at a quarter of the soy’s weight, and four spices, and cook it covered until it coats a spoon. Taste any sweet soy, homemade or bought, before dressing the bowl.

What goes on top

Every shop has its own mix, but the same few things recur.

Dunlop’s basic bowl has four seasonings: garlic pounded with a pinch of salt and loosened with cold water, chili oil with some of its sediment, sweet soy sauce and crisp fried peanuts. Some cooks add crushed sesame or soybean flour instead of peanuts. Her sesame version adds sesame paste thinned with oil, a little sesame oil and crushed toasted sesame. Richer bowls use chili oil, brown-sugar syrup, sesame paste, ordinary soy sauce, sweet red soy, garlic paste and toasted sesame all at once.

The garlic goes in as “garlic water,” 蒜水: raw garlic pounded and loosened with water. Six or seven cloves pounded to a paste with three tablespoons of cool water is enough for four bowls; it does not keep, so it is made fresh.

Sold from carrying poles since at least 1909

Sweet water noodles have been sold on Chengdu’s streets for well over a century.

An early record is in Chengdu Tonglan, a survey of city life by the late-Qing Chengdu writer Fu Chongju. Its first volume came out in September 1909 and the rest the next year: eight volumes and some 700,000 characters, from geography to trades. In 2025 it was published complete for the first time. Among the snacks it lists that Chengdu still eats are buckwheat noodles, tangyuan and sweet water noodles.

Fu put sweet water noodles among the foods sold from carrying poles and recorded the price: 16 wen a bowl at a restaurant in the morning, 6 wen from a street seller. The food writer Jiang Shu explains the gap: a carrying pole paid no rent or taxes. Even so, he adds, such snacks were bought less by the poor than by wage earners and people of leisure. Fu was not a fan. 太粗无味, he wrote: “too thick and tasteless.”

Locals have their own version of the story, which Dunlop passes on: that the noodles first appeared at the end of the Qing dynasty in the old imperial city, around today’s Tianfu Square, sold by peddlers, and became a famous local snack around Baiyun Temple only in the 1940s.

Where to eat them in Chengdu

Look for them in old-style snack shops around Wenshu Monastery, especially in the morning.

The streets around Wenshu Monastery are the classic place to look. When Dunlop visited for The Food of Sichuan, she singled out Dongzikou Zhang Lao’er Liangfen, opposite the monastery, where sweet water noodles were a house specialty and a team of servers dressed each bowl at speed and passed it through a small window. A prize-winning 2020 essay by a visitor from Dalian describes another shop in the same area, in a lane of Wenshufang, early in the morning: a glass case holding a dozen or more seasonings, bowls of plain, finger-thick noodles waiting beside it, and an owner who turns one into a red, glossy bowl scattered with sesame and crushed peanuts in moments. Stir it, and the noodles take on the sauce; the writer ordered a second bowl.

Sweet water noodles are sold alongside other cold snacks such as liangfen, and many people eat them for breakfast. Some shops also offer a sesame version, 芝麻甜水面, with sesame paste in place of peanuts.

Relatives: Zhong dumplings, dan dan and cold noodles

Most Sichuan noodles are thin and alkaline. Sweet water noodles are neither.

The closest relative is Zhong dumplings, small pork dumplings in the same sweet soy, chili oil and garlic. In old Chengdu all carrying-pole noodles, sweet water noodles included, counted as “dan dan noodles” in the broad sense: snacks to stave off hunger, sold by the liang and never meant as meals.

To a newcomer, Chinese Cooking Demystified joke, much of the Sichuan noodle world looks like “noodles with chili oil, MSG and soy sauce,” and the way to sort it is by the noodle. Dan dan noodles, Yibin burning noodles, Chongqing xiaomian, cold noodles and Leshan’s MSG noodles all use thin alkaline noodles; sweet water noodles use thick, non-alkaline ones. Sichuan cold noodles take almost the same dressing, seasoned soy, garlic water and chili oil, plus vinegar and Sichuan pepper. Put the two bowls side by side and the difference is the noodle: the sweet soy is what you taste first, but the noodle is what sets the dish apart.

Sweet water noodles at home

Make the sweet soy and chili oil first; the noodles take about 45 minutes.

This is Dunlop’s recipe for two bowls. Make the sweet soy in advance (recipes in the table above) or use a bought one; any Sichuan-style chili oil with plenty of sediment will do.
