The Praça da Bandeira, an area of Rio that until recent years was mostly known for prostitution and cheap inner-city housing, is rapidly changing. Lying in the shadow of the massive Maracanã Stadium – built for the 1950 World Cup and the planned location of the opening ceremony of the 2016 Summer Olympics – it is alive with new construction and pedestrian traffic, which are changing the tired face of this historical but underappreciated neighborhood. And sitting snugly in the midst of this new buzz is Aconchego Carioca, a restaurant and bar with one of the best beer menus in Rio.

In the windy coastal region south of Barcelona, surrounded by the wide vineyards of Baix Penedès, entire families are decked out in winter gear and ready to eat … some salad! In the late 19th century, the word xató (pronounced “sha-TOH”) first appeared in writing in the Catalan press. Just as the name for the dish paella is borrowed from the name of the pan that is used to prepare it, xató originally referred to a sauce, but is now the name for a specific salad preparation. Practically unavoidable in the towns of Baix Penedès, Alt Penedès and Garraf (sub-regions that lie between the provinces of Barcelona and Tarragona), xató is surprisingly rare on restaurant menus in Barcelona proper, just under an hour away.

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.

Horn of plenty, yellow foot, ox tongue, gray knight: the bewitching names are like something out of a fairy tale. But at Casa Lucio, in Sant Antoni, these are all mushrooms you might find on your plate, especially in autumn.

In Mexico, the land of eternal spring, something good to eat is always in season. We ravenously await the arrival of artichokes in March, mangos in April, fresh corn in September. Even the wriggly little gusanos de maguey (maguey worms) which appear in May are wildly anticipated – by some. Change in season is subtle here, but essential to the survival of the country. But seasonal lines are blurring. Asparagus rears its tasteless Chilean head all year; pallid strawberries are found in December. Seasons have gone global and our palates suffer for it. Which is all the more reason to pay attention to what’s local now. From July into October, coinciding with our temporada de lluvia, wild mushrooms, spurred on by rain and humidity, hit the markets of central Mexico. Here in the capital, the month of August is high ‘shroom time.

In just a few hours, Germany will play Brazil in a World Cup semi-final match, but the outcome doesn’t matter. Win or lose, Germany has already conquered this nation – gastronomically speaking, at least. This isn’t fancy gastronomy, of course (leave that to the French!), but the simple, hearty, delicious food that the best Brazilian German bars serve all over the country, especially in Rio. German bars have been beloved institutions in Rio for a very long time. The most famous ones have been around since before World War II, when Rio was the capital of the country and the federal government was flirting with German's National Socialist Party. By 1939, Rio had a dozen German bars.

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.

Editor’s note: Award-winning cookbook author, chef-restaurateur and television personality Rick Bayless is a renowned expert on Mexican cooking and a frequent traveler to Mexico City. He recently shared with us his list of must-visit places in Condesa, Roma/Roma Norte and Polanco.

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.

Dear Culinary Backstreets, My husband and I are headed to Rio for vacation and neither of us eats meat or fish. Brazil sounds like a paradise for the carnivorous, but what’s a vegetarian to do?

Now that ski season has begun in Catalonia, thousands of Barcelonans make the pilgrimage every weekend to the Pyrenees. But winter sports are not the only draw; this is also the time to enjoy the cooking at masias, traditional farm buildings that have been converted into restaurants.There, the smells of winter stews and dishes made with mushrooms, game, mongetes (beans) and butifarra (a kind of pork sausage) are motivation enough to arrive at the village early and in one piece.

As a chill sets in and heavy clouds roll over Istanbul, turning the Bosphorus battleship gray, we say goodbye to the luscious strawberries and blood-red tomatoes in the market. Fall marks the start of hamsi season, a time when small anchovies fill the nets of fishing boats on the Black Sea coast, squirming their way – with all of the country’s anticipation – onto grills and into pans and ovens throughout Turkey. The colder and rainier it gets, the fatter and cheaper the hamsi become.

Mushroom hunting has an irresistible, magical pull. Composer John Cage, an avid mushroom collector, found them an integral part of his creative process, once writing: “Much can be learned about music by devoting oneself to the mushroom.” Every fall, thousands of Catalans likewise find themselves under the mushroom’s spell, following the elusive fungus’s silent melody into the woods, a rustic wicker basket in one hand and – more and more these days – a GPS-enabled smartphone in the other.
