The official cold blew in last month. Winds pierced thick cotton clothing through to the skin, into the body and further into the bone while we were driving in the open rickshaw, after the sun slipped down. Then it rained and thundered, the kind that makes one jump with the clap. When the morning air hit the airways, balminess laced with pollution infiltrated the atmosphere. To get and stay warm is work here. We seek out the afternoon sun to heat our bodies and dry our clothes. Another way to keep the chills at bay is to ensure a supply of dense foods and hot liquids.

Traditional Chinese Medicine (TCM) is all about balancing your yin and yang, a system that involves dietary practices as well as exercise, massage, acupuncture and herbal medicine. Winter is considered a “yin” season, meaning that it is cold and damp, and you should therefore eat warming, or “yang,” foods to balance out the external conditions.

Hairy crab season is once again sweeping Shanghai’s diners into a frenzy, with the bristly crustaceans popping up on street corners, in streetside wet markets and, most importantly, on dinner plates. This year we’ve even seen reports of elaborate live crab vending machines hitting the streets in Nanjing and an attempt to start a black-market trade in German crabs.

There’s a light scent but not much taste to the fresh truffle we just picked up from a local Chinese market. On a tea scale it weighs in at 18 grams and is the size of a healthy walnut. This year’s price for fresh truffles from France or Italy is many times more than the roughly US$6.50 price tag for this earth-coated Chinese truffle (松露, sōnglù).

When the seasons change from summer to winter, your body requires different foods to stay healthy – as anyone who has come down with a fall cold can attest. Traditional Chinese Medicine (TCM) says that the changing temperatures result in a dry season, medicinally speaking, meaning that your body lacks fluids, affecting your lungs and throat, as well as your digestive systems. Autumn is also a chance for you to build up your body’s immunity before the harsh winter. Nourish yourself with these foods now, and you’ll be thanking yourself when winter sets in.

In Catalonia around the summer solstice, we make one of our most traditional liqueurs, ratafía, for which the herbs, fruit and flowers that are macerated in alcohol must be collected on Saint John’s Eve, or June 23. This highly aromatic digestif has long been believed to have medicinal properties. There’s even an old Catalan rhyme along those lines: Ratafía, tres o cuatro al día (“Ratafía, three or four per day”). Different versions of the liqueur have been made for centuries in eastern Spain and some regions of France and Italy but, like the other herb liqueurs throughout Europe, they originated from the Ancient Roman and Greek custom of macerating fruit and herbs in wine, from Arabian perfume distillation and from the sophisticated medieval distillations in monasteries and convents that created the first aguardientes, or grape-based, medicinal liqueurs.

The cuisine of Antep deserves every bit of the praise it receives. In the southeastern city known as the gastronomic temple of Turkey, the world’s most refined kebab traditions are obsessively guarded by a cadre of traditional ustas in the local grilling institutions. Baklava workshops are steeped in an odd mixture of science and voodoo that would titillate Willy Wonka himself. But coming down from a grilled meat and sweets binge, the body wants dolma, pilav, börek and çorba – the home-style food that is strangely absent in Antep’s restaurants.

Spring arrives at the markets in Istanbul with a great deal of color and fanfare. Vendors arrange peas in perfect diagonal rows, displaying their goods to lure you into a multi-kilo purchase. Men furiously carve out artichoke hearts and toss them into lemon-water-filled bags, step around massive piles of trimmings and hand you what feels like a new goldfish purchase. Fava beans are ubiquitous in their fuzzy pods, although less appealing because of all the prep work that comes with them. Best to enjoy fava beans in a restaurant, zeytinyağlı-style (with olive oil) and or in our favorite preparation, a garlicky mash like the chefs make at Müzedechanga in the Sabancı Museum.

With all of the anticipation of local elections in March, the scandalous graft-laden tapes leaked via social media, the communication fog brought on by the ban of Twitter and YouTube and the subsequent call for a vote recount in many cities, this city's stomach had good reason to be distracted. But one cannot survive on a diet of daily news alone. In case you all forgot, Spring is here.

In the weeks leading up to Easter, Barcelona looks like an extension of Willy Wonka’s factory-fun house: chocolate castles, houses, animals, cars, motorbikes and even cartoon characters and fútbol celebrities fashioned out of cacao populate the city’s traditional patisseries. Catalonian confectioners expect to sell some 600,000 chocolate sculptures decorated with yellow chicks, chocolate eggs and cakes studded with hard-boiled eggs and colored feathers this year. The last are known as monas, and godparents traditionally give these to their godchildren throughout Catalonia and other parts of Spain to mark the holiday.

Editor’s note: Sadly, it appears that due to the neighbors no longer wanting to be surrounded by fish fry odors, this restaurant is no longer serving hamsi. We will update if things change. Around the time that hamsi, our favorite little fish, appear in the markets of Istanbul in late fall we become restless for the Black Sea-style cooking we’ve been missing since the previous season. Hamsi (fresh anchovies) are not the only thing to eat in a Black Sea restaurant, but eating in one that doesn’t have hamsi sometimes feels like sitting down for a meal in a BBQ joint that only serves coleslaw.

Shanghai’s hottest summer on record is officially behind us, which can mean only one thing: Mid-Autumn Festival is just around the corner. Zhōngqiū jié (中秋节) is that memorable time of year when Chinese people gift (and regift) bite-sized treats known as mooncakes (月饼, yuèbǐng).

Editor’s note: This is the fourth installment of “Spring (Food) Break 2013,” featuring our favorite foods of the spring season in each city Culinary Backstreets covers. This year’s Nevruz celebration, an ancient welcoming of spring, may be remembered for its political significance in which a peace deal was struck between Turkish leaders and Kurdish rebels. But once the shoulder-shrugging, line-dancing, fire-jumping and ululating are over, the real bounty of the season will continue to be celebrated all over Turkey and in many Istanbul restaurants, from the chic to the shabby.

As the legend goes, a 19th-century Catalan farmer was out experimenting in his fields when he came up with a new kind of longer, juicier green onion, the calçot. In creating the onion, the farmer produced much more than a new vegetable; he also paved the way for the rise of an idiosyncratic, and distinctly Catalan, cultural event.

We are unabashedly fanatical in our love of hamsi, or anchovies, a late fall/wintertime specialty whose arrival we eagerly await each year in Istanbul, where the tiny fish are most commonly served pan-fried, grilled or in pilaf. But as any hamsi aficionado knows, for the best anchovy-eating in Turkey one must go directly to their source: the country’s Black Sea coastline, where the catch is brought in.
