The Chinese have appreciated the finer qualities of roast duck for millennia, and in that time, they’ve refined their cooking techniques into a virtual art form. The first mention of roast duck (烤鸭, kǎoyā) dates back to the Northern and Southern dynasties (A.D. 420–589). By the Yuan Dynasty (1206-1368), the tawny bird was gracing the tables of mandarins and emperors in then-capital Nanjing, and imperial kitchen inspector Hu Sihui mentioned it in The Complete Recipes for Dishes and Beverages, published in 1330, along with a record of how the duck was cooked.

In Shanghai, a pretty surefire way to tell whether a dining establishment deserves your attention or not is by the presence of a line in front of it. (A corollary might be that the amount of attention the place deserves is commensurate with the size of the line.) Lao Shaoxing Doujiang passes the test. This ramshackle stand in the Huangpu district serves traditional breakfast foods all night long. Until recently, the stand was run by a granny in her nineties who would ladle out bowls of hot soy milk (豆浆, dòujiāng) into the wee hours of the morning. She retired this year, but her less-than-friendly son has taken over, and the buzz remains (as does the inevitable line).

Dear Culinary Backstreets, My family is planning a trip to Shanghai. We want to dine like the locals but also make sure our little ones get their fill. Do you have any recommendations?

It’s been two weeks of cycling through China’s Qinghai province, and the food selection is slim. The majority of the province sits on the vast Tibetan Plateau, well above the tree line in conditions too harsh for significant cultivation. Yaks graze on well-trampled grass as far as the eye can see, with white yurts and colorful prayer flags dotting the hillsides and each summit pass. By Chinese standards, six million inhabitants in the country’s fourth-largest province make Qinghai practically deserted. For long stretches, only nomadic yak herders can be spotted between the tiny villages. Stopping for a roadside lunch in the small, isolated towns inevitably means a bowl of either mutton or yak chopped-noodle soup (羊肉面片, yángròu miàn piàn or 毛牛肉面片, máo niúròu miàn piàn). Served up in a tomato-chili broth, it’s a tasty meal, but repeated daily, it inevitably becomes tiresome. Additional ingredients sometimes includes julienned zucchini or green peppers, depending on the remoteness of the particular town and their staggered vegetable shipments. After just one week, we’re eagerly awaiting more fruitful pastures, and Sichuan province, located just to the east on our route, is a culinary paradise.

At the dusty eastern edge of the Taklamakan Desert, the ancient city of Dunhuang marked the intersection of the northern and southern parts of the Silk Road. Meaning “Bright Beacon,” Dunhuang was a historical refuge for weary travelers peddling their wares along the trade route, and this confluence of cultures influenced the ancient city’s cuisine. Merchants brought spices and cooking techniques from the West that combined with Chinese imperial culinary traditions and local ingredients.

Dear Culinary Backstreets, I keep hearing about something in Chinese cuisine called “stinky tofu.” Does it really smell that bad to earn such an offensive moniker?

The vast country of China has just one time zone, so Shanghai’s East Coast location means darkness comes early and most residents usually eat by nightfall, with restaurants often closing their kitchens around 9 p.m. But for those who keep late hours, nighttime brings out a chorus of pushcart woks and mini grill stands to street corners around the city. Despite often aggressive government crackdowns on these tasty, yet mostly unlicensed, food stands, the migrants who run them are determined to make a living and feed the masses while they’re at it. Our top five list goes beyond these roving vendors to feature a mix of restaurants that stay open late and small family-run gems that cater exclusively to the night-owl crowd.

It’s not every day that you find a former national volleyball champ in the kitchen, but that’s just the case with Lu Dajie (aka “Big Sister” Lu) and her eponymous restaurants. After a successful career with the Chinese military’s volleyball team, followed by years working in restaurants for others, she left her hometown of Jianyang in Sichuan province with her brother, bringing her region’s famous cuisine with her. Now, in Shanghai, she is slowly building an empire.

Editor’s note: This week we are celebrating street food, in all its fascinating, delicious and sometimes offbeat forms. Each day, we’ll take a look at the top street foods in a different city that Culinary Backstreets covers. This feature from Shanghai is the first installment. 1: Shengjianbao A Shanghai specialty, shēngjiān mántou (生煎馒头) – or shēngjiān bāo (生煎包), as they’re known everywhere else in China – are juicy pork buns wrapped in bread dough, then arranged in a flat, oil-slicked wok in which the bottoms are deep-fried till they are crispy. Although shengjian mantou can be found on most street corners in the morning, we’re especially fond of the delicious misshapen buns at Da Hu Chun. A Chinese Time-Honored Brand (老字号, lǎozìhào), Da Hu Chun has been splattering grease since the 1930s and, nearly 80 years later, has six restaurants across Shanghai. The venue’s chefs use the rare “clear water” technique, frying the pinched side of the dough face-up to create little Frankenstein buns that might not be as photogenic as the more common “troubled water” variety, but that have a thinner skin that gets extra crisp – and we’ll sacrifice good looks any day if it means better flavor.

Drinking báijiǔ (白酒) always brings us back to our first illicit taste of hard alcohol – a shock to the system, going down fiery and leaving a shudder-inducing aftertaste on the tongue. And just as many first-time drinkers are left wondering where exactly the attraction lies, the same thing is true for baijiu – at least, until the aftereffects start to kick in. In fact, even the Chinese believe that one needs to drink 300 shots over time in order to truly understand the appeal of baijiu.

In 2008, Shanghai’s noodle scene was dealt a mighty blow. A Niang, a granny from the ancient seaport of Ningbo who was famous among local foodies for her seafood noodles, was forced to close her streetside shop after being diagnosed with kidney disease. Over the past few decades, she’d gained a loyal following; her friendly, wrinkled face was a common sight in the dining room, as she often wandered through the hordes of hungry diners to say hello to regulars or wipe up a splash of spilled soup.

On the diner intimidation scale, Shanghai’s Chenghuang Miao Tese Xiaochi – which can be loosely translated as “City God Temple Snack Shop” – ranks pretty high, with aggressive lunchtime crowds and nothing but Chinese character-laden menus for guidance. But the payoff, a baptism by fire in authentic Chinese eating, is worth it. The hungry masses that congregate here have discovered a simple truth: the food here is quick, tasty and cheap – a gastronaut’s holy trinity.

Ever since former President Deng Xiaoping opened China’s economic doors to the rest of the world starting in 1979, foreigners wishing to do business in China have had to find a local partner to form a joint venture company. Though no longer a hard-and-fast requirement, that’s still the modus operandi at Lotus Eatery, where a founding partnership brings together the best of both culinary worlds: unusual yet authentic local flavors and distinctly foreign notions of consistent quality and attentive service.

Lantern Festival (元宵, yuánxiāo, or “first night”) is the fifteenth day of the Chinese New Year, and marks the last day of Spring Festival. This “first night” is actually the first full moon of the lunar new year, and in the Year of the Snake it lands on February 24. On this holiday, it’s customary for revelers to light red lanterns and eat sweet stuffed dumplings called tāngyuán (汤圆).

Good service in China is a relative term, and the longer you live here, the lower your expectations sink. The Michelin Guide allegedly won’t deign to cross over the Hong Kong border into China because they refuse to sully their white-tablecloth reputation by doling out stars to restaurants with subpar service. But the inspectors must have never entered a Hai Di Lao Hot Pot, or they might have to change their tune.
