“The Price of Cold” — the story of my recent adventures exploring China’s artificial cryosphere — is now online in The New York Times Magazine. In it, I visit the world’s first and only frozen dumpling billionaire, hang out with the chef leading a one-man refrigeration resistance movement, and visit refrigerated warehouses and R&D labs across the country. In my completely unbiased opinion, it’s a lot of fun, and you should read it right now — and then share it with all of your friends!

Meanwhile, for those of you for whom that is not enough refrigeration for one weekend, I compiled this list: ten stand-out destinations for the armchair Chinese cryotourist, based on my own travels while reporting the story.

From the “Room of the Sleeping Fish” in Jinan to a Wal-Mart in Zhengzhou, these places are both extremely obscure and yet globally significant. Together, they help tell the story of how refrigeration is changing the way Chinese people farm, eat, and shop — in exactly the same way it changed the American and European landscape and diet, and yet, of course, with a uniquely Chinese twist.

1. Sanquan Headquarters, Zhengzhou

Chen Zemin is the official Father of Frozen Food in China, Sanquan is his frozen dumpling company, and frozen dumplings are the the Swanson’s TV Dinner of China — the gateway convenience food paving the country’s path towards a future of chilled prepared meals and frozen entrees. My New York Times Magazine story includes these facts and much more besides, including Chen’s life story and a gorgeous photograph of the Sanquan factory floor taken by Massimo Vitali.

But neither my words nor Vitali’s photo quite bring to life the mesmerising process of making 100,000 dumplings an hour. For that, until your next visit to Zhengzhou, you will have to make do with these iPhone videos (forgive the quality).

2. Wal-Mart, Zhengzhou

Zhengzhou, as those of you who have read my article know, is the capital of frozen food in China. “Think of Kansas City, but double the size,” explained Ralph Bean, who, as director of the United States’ Agriculture Trade Office in Beijing, is tasked with getting U.S.-grown ingredients into China’s frozen dinners of the future.

In other words, it’s a third-tier city of nearly 9 million that boasts one brand new subway line (it opened in January) and three Wal-Marts. I visited the Manhattan Plaza branch in order to spot Sanquan dumplings in the wild, and to see who bought them, and why. This lady explained that she liked them because they were a new, modern kind of product.”They didn’t exist before,” she said, as if that were reason enough to have them for dinner.

Meanwhile, the packaging emphasised frozen food’s classiness (“enjoy the elite flavour”) and convenience, listing the “Three Withouts”: you can eat these without chopping, without having to wash anything, and without seasoning. The store’s tiny frozen food section was dominated by dumplings, with some dubious-looking meat popsicles and a lonely “Children’s Steak” ready-meal rounding out the options.

Elsewhere in the supermarket, store-made fresh dumplings were for sale behind a sneeze-guard and raw meat was laid out on ice and handled with tongs, in stark contrast to the Zhengzhou wet market (see destination 3, below). But fish is sold live, even at Wal-Mart, and the front wall was covered with scoop-your-own seafood tanks.

3. Wet Market, Zhengzhou

Zhengzhou’s largest wet market happened to be right next to my hotel, which made the 5 a.m. start to visit it a little easier (but not much). These chicken had been slaughtered at the farm this morning, the vendor explained, and he would sell them all today.

When I asked how he kept the meat fresh, he looked confused, and replied, “It’s winter!” In summer, apparently, a regular hose-down with cold water (hence the name “wet” market) and a standing fan do the trick. “If I don’t sell it all by evening,” he shrugged, “I’ll just send it to the hotels.”

Other vendors had their own small freezer chest, or rented space in the refrigerated walk-in beneath the market, but they all explained that their customers preferred fresh meat. In January, they told me, rabbit and dog stays fresh in the open air for a couple of days at least; duck lasts two or three days; and mutton can sometimes be fine for nearly a week.

Once I saw the market’s communal refrigerated walk-in, with its funky smell and collapsing cardboard boxes piled high on the concrete floor, the pervasive idea that unrefrigerated, but freshly slaughtered, meat was fresher than its refrigerated counterpart made a lot of sense.

Tim McLellan, a tireless advocate for all things cold chain and a director at Preferred Freezer Services, an American company that is about to open its third cold-storage warehouse in China, told me that, while touring some of these older facilities, he had even seen rats. When I expressed surprise that they could survive in the cold, he explained that they live inside the wall insulation, and brave the chill to chew through boxes and gorge themselves.

In any case, this particular cryospheric landmark may not be around for much longer. According to McLellan, both the wet market itself and its outdated cold storage are endangered spaces in today’s China, given the government’s ambitious cold chain modernisation and supermarketisation plans. “That’s what the government wants to do, is shut them down,” he said. “It just takes time.”

IMAGE: Live fish transportation requires an octopus-like exoskeleton of liquid oxygen hoses.

Outside the market, men unloaded a lorry-full of live fish, which is transported using an incredibly complex truck-bed system of Styrofoam boxes, running water, and oxygen tanks, all laced together with a spaghetti-like profusion of hoses.

As in Wal-Mart, so too in the wet market: in China, fish is just not fresh unless it’s still alive.

4. Longjing Caotang, Hangzhou

IMAGE: Catching my dinner, Hangzhou.

The freshest fish I ate in China, however, was at a restaurant called Longjing Caotang, in Hangzhou. Dai Jianjun, its chef-owner, serves a “prelapsarian Chinese cuisine,” to borrow Fuchsia Dunlop’s description from her wonderful New Yorker article about the place. Everything I ate had been pickled, dried, preserved in-house, or freshly foraged that day.

IMAGE: Dai’s bamboo fish-drying hut.

Dai’s depth of knowledge about traditional Chinese flavours — he can and did talk for hours about the importance of orientation and bamboo-rod spacing when wind-drying sausages, or the under-appreciated difference between small-leaf and large-leaf pickles — is only matched by his dislike for all things modern. “City food gives me the shits,” he said, before quoting two ancient Chinese philosophers to explain that agriculture had first gone wrong by harnessing oxen to the plough, rather than relying on manpower alone.

But, though it’s easy to laugh at his quirks and disagree with his fetishisation of some kind of Utopian, originary foodscape, Dai is almost single-handedly managing to preserve and revive the kinds of micro-local, pre-refrigeration techniques and flavours that are increasingly rare in contemporary China.

As Fuchsia Dunlop puts it, “Dai’s main worry is that traditional farming and cooking won’t survive another generation.”

When I spoke to Jim Harkness, Senior Adviser on China at the Institute for Agriculture and Trade Policy, he confirmed this prognosis:

The unfortunate thing is that, on the one hand, the economic boom and things like more modern food distribution systems and cold chain allows for a far more varied diet for many people in China — but it’s a varied diet in which a lot of the traditional foods are dying out. They desperately need a Chinese Slow Food movement. You’re simply not going to be able to find a lot of those traditional foods as capitalism develops and people can’t or are not willing to invest time in food preparation. And, of course, food safety regulations make it harder for a lot of the traditional practices and enterprises to continue. The knowledge is disappearing, and I think that’s a real shame.

I sincerely hope Dai’s fish-drying hut is not also an endangered species. Nonetheless, no Chinese cryo-tour would be complete without a stop at Longjing Caoting, to experience the kinds of foods that refrigeration — and its companions, urbanisation and a rising GDP — threaten to make extinct.

5. The Room of the Sleeping Fish, Jinan

IMAGE: Owen Guo, my wonderful interpreter and fixer, being instructed in the art of sending fish to sleep.

Fish are the anti-frozen dumpling: unlike Chen Zemin’s rice balls, they have no legs, both literally and metaphorically. But, at China’s National Engineering Research Centre for Agricultural Product Logistics in Jinan, sandwiched between the “Time/Temperature/Tolerance Laboratory” and “Small-size Instruments Storage,” the curious cryo-tourist can visit “The Room of the Sleeping Fish.” As I describe in a forthcoming issue of Harvard Design Magazine, the Centre’s scientists have developed a way to ship live fish out of water, by using refrigeration to induce a sort of suspended animation.

According to the technician in charge of the process, the fish are sent to sleep by gradually lowering the temperature of the water, half a degree at a time over the course of twenty-four hours, to just above freezing. In this sluggish state, a fish can be rolled up, popped in a clear plastic poster tube, and mailed to anywhere in China. As long as they arrive at their destination within three days, the Centre’s Director explained, they will simply wake up and start swimming again as soon as you slide them out of the canister.

What’s more, he added, these revived sleeping fish taste better than the freshest just-caught fish: the whole process is apparently the piscine equivalent of a spa retreat, and the less stress, the better, as far as fish flesh and flavour are concerned.

6. XinFaDi Agri-product Wholesale Market , Beijing

According to official statistics, less than five percent of China’s vegetables are transported under refrigeration. An early morning visit to the XinFaDi wholesale market, which supplies more than 70 percent of Beijing’s vegetables, demonstrates the reality behind that figure. Eggs, grains, oils, and, curiously, mushrooms are all sold from inside a covered structure, but fruit and vegetable transactions are handled in the parking lot, at the back of each delivery truck.

And, of course, the trucks are not refrigerated. Instead, vendors pack the vegetables tightly under layers of blankets, ice, and even hay, excavating each radish or head of broccoli individually for their customers. As I explain in the story, it’s thus perfectly normal for a quarter of the cargo to rot before it can be sold — more in summer.

7. Yantai Quanyuan Fruit & Vegetables Co. Ltd., Qixia

“Chinese apple move toward the world from here,” proclaims the slogan on the side of one of the largest modified-atmosphere, refrigerated apple-storage facilities in China. Quanyuan uses German-designed equipment to store the apples at 0 degrees Centigrade. Flushed with nitrogen, in order to remove oxygen and slow respiration still further, the apples stay fresh for a year. The company exports its product across Asia, to Africa, and, most recently, to Canada. Soon, they hope, their apples will be allowed into the United States.

The company’s owner, a tall, unsmiling man wearing a blue suit with a gold tie, told me that when he was a boy, his family would wrap the apples from their orchard in paper and put them in a specially dug hole, near the house, so that they’d last the five or six months from harvest to lunar new year. “Still,” he remembered, “they were always wrinkled and soft. These fruits are screwed without refrigeration.”

The modified-atmosphere technology, which is standard in the United States, was introduced to the Chinese apple-growing region of Yantai in 1994, and it has changed everything for Quanyuan.

“Before, I lost a lot. It was tough,” he said, in a matter of fact tone. “Now, I lose less than 1 percent of my apples.” Standing in front of a photograph of himself shaking hands with a senior member of the Party’s standing committee, he added, “It took me three years to pay the construction of these warehouses back, but we started exporting in 2000. I see huge potential.”

8. Beijing Vegetable Research Centre, Beijing

Liu Sheng, at the Beijing Vegetable Research Centre, is developing the optimal post-harvest regimes for Chinese produce. These were developed for British fruit and vegetables beginning in the 1920s, and UC Davis’ Post-Harvest Technology freely disseminates separate sets of specialised guidelines perfectly tailored to the unique metabolic profiles of Anjou pears and Bartlett pears, or Red Delicious apples and Golden Delicious apples.

“We have some for Chinese vegetables, but ours are not as specific,” Sheng explained. “We have a single standard for thirty different fruits!” He spends his time measuring loss rates between batches of bitter melon that have been hydrocooled versus those that have been exposed to forced-air precooling, and assessing organoleptic deterioration in hawthorn berries when stored at 3 as opposed to 4 degrees Celsius. Personally, he is a big asparagus fan.

Sheng also helped plan one of the Party’s flagship cold chain projects, the “South to North Vegetable Transfer.” Launched in 2011, this “Pilot Program of “Modern Agricultural Circulation” aimed at repurposing the country’s southernmost, tropical island province, Hainan (otherwise popular with Chinese honeymooners), into the “National Winter Vegetable Base,” complete with 30 brand new logistics centers and an express refrigerated rail-link to Beijing.

In other words, just as drought conditions in California are driving up fruit and vegetable prices across the United States, the Chinese are racing to turn Hainan into their Central Valley.

Meanwhile, his colleagues, as I mention in the magazine story, are breeding varietals that are better adapted to cold storage in the first place. As we looked across the street at the purple-lit greenhouse dedicated to their research, Sheng admitted that he thinks this will result in a loss of flavour, because “you can’t have both.”

9. Yogurt Control Room, Yili, Tianjin

A traditional Chinese diet involves very little dairy: cheese is viewed as disgusting, butter is indistinguishable from cheese, ice-cream is only for kids, and the majority of the population is lactose intolerant. But, with the temptation of such a huge market, and equipped with a growing cold chain through which to reach it, both international and Chinese companies have pushed a “yogurt strategy” to “reintroduce dairy,” as Chris Brimlow, Nestle’s Director of Research and Development in China, told Paul Roberts in The End of Food.

“Even as adults, in only takes three months to develop the enzyme,” Brimlow says. “They may feel sick for a little while, but they get used to it.”

Yili is the market leader, achieving success with its locally attuned flavours (sweetcorn and aloe, as opposed to Danone’s strawberry) and with a clever marketing campaign that pushes yogurt as good for teenage complexions. I visited the newest of its ten yogurt factories, in Tianjin, built to anticipate a demand that is projected to grow by 20 percent year-on-year for the next decade.

With consumer confidence shaken by the country’s milk powder scandals, Yili were anxious to show me their rocket-ship style Yogurt Control Room, which includes a real-time map of the company’s GPS-enabled refrigerated trucks that I wasn’t allowed to photograph. “We want customers to know about our cold chain system in order to build trust,” the oily PR representative told me. “So we made an infographic.”

10. Express Channel Food Logistics, Beijing

Liu Peijun got his start persuading wary Beijingers to try Sanquan’s frozen dumplings back in 1996, when they first reached the capital’s supermarkets. He personifies China’s new wave of homegrown logistics entrepreneurs: ambitious (he is expanding to Shanghai), successful (a Jeep, a BMW, and plans to send his son to college in the U.S.), and as frustrated by the missing links in China’s cold chain as he is proud of his pioneer status.

We went out for Mongolian hotpot to warm up after our refrigerated warehouse tour. As I struggled with how exactly to eat a duck’s tongue, he said, “I have to admit, business is good.” From the way he smiled, it was easy to tell that business was very good indeed. In fact, Liu added, cold chain logistics is so hot in China right now that the interpreter he brought with him last year on a fifteen-day research tour of refrigerated warehouses overseas quit as soon as they got back to Beijing, in order to start a cold storage business of his own.
