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.

La Boquería is undoubtedly one of the most famous markets in the world, but there are 43 markets spread across Barcelona, each with its own unique charms. Once a year, they can be experienced all at the same time, in the same place. From October 17 to 19, 265,000 visitors thronged the square in front of Barcelona Cathedral for the fifth edition of the Mercat de Mercats (Market of Markets) festival, which gathered 40 stalls, 30 local artisan producers, 40 chefs with 17 Michelin stars between them and 14 of the city’s best restaurants. The festival offers an amazing opportunity for locals and tourists to taste the dazzling array of Catalan flavors and to get to know the city’s neighborhood markets.

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.

[Editor's note: we're sorry to report that Butifarring is now closed.] Gourmet fast food has swept through Spain at full speed. It comes in multiregional styles and with strong creative inspiration behind it – and, most importantly, the food itself can be exceptional.Eric Camp, Albert Gómez and their three partners are a good example of this, with their sausage-centric project, Butifarring, and their first small venue in Barrio Gòtico, which is much more than a Catalan hot dog or sandwich place.

Editor's note: We are sad to report that SofrAda has closed. One of our favorite spots to make a quick summer getaway from Istanbul is the idyllic car-free and forested paradise of the Princes’ Islands, located just a short ferry ride away from the city. Here’s where you should eat when you get there.

Just a block away from Mexico City’s financial district, one unlikely food star sets up shop every morning. From Monday to Saturday, at La Abuela, 72-year-old Arnulfo Serafin Hernandéz feeds hungry office workers, commuters, neighbors, school kids, government officials and tourists from all over the world with one of the simplest Mexican dishes: tacos de canasta.

If it’s because of showing visitors around or simply a desire to get away from the city for the day, we can usually count on at least one visit a summer to Büyükada, the largest of the Princes’ Islands. But as much as we like looking at the car-free island’s Victorian mansions and visiting its quiet, forested backside, when it comes time to eat on Büyükada, we feel like we’re stuck inside an airport, forced to eat mediocre food at outrageous prices. (Although we very much like the food at Kıyı, a seaside restaurant on the island that we’ve previously recommended, even a casual dinner there ends up costing more than what one would like.)

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.

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.

Perhaps coffee is underappreciated in Rio because it’s so plentiful. Brazil is the world’s largest producer of coffee, but both the selection and the presentation of the stuff you’ll find in Rio is hardly what a gringo dreams of in the capital country of café. Coffees here are cafezinhos, small, potent, highly sugary and with no milk. A cafezinho is taken standing up at a lanchonete (snack bar) or on a work break in the office in tiny medicine cups filled from an unseemly plastic cylinder. When Brazilians have seen the size of our morning coffee, many have expressed a concern that we could hurt ourselves with such a large quantity. (It’s just a coffee cup.)

Churros, the long, skinny, crenellated, sweet fried crullers made from just flour, water and salt, have been enjoyed for centuries in Spain, with hot chocolate and without. However, in Barcelona, xurros, as they are called in Catalan, are becoming an endangered species. In recent years, more than half of the xurrerias in the city have disappeared. Many of the old-timer xurreros who still survive have the odds stacked against them: permit renewal for a street stall is near impossible; rent has become prohibitively expensive and continues to increase; or required updates to old infrastructure might prove extremely costly. However, we know of one young newcomer who has emerged with fresh energy and inspiration, incorporating lessons from the masters in his creative take on xurros. The best way to save this endangered species is to eat it, so here are our five favorite xurrerias, which make these star-shaped doughnuts with great care – and with delicious results that are worth seeking out.

Editor's note: Our third installment in the Global Bar Crawl takes us to Barcelona, where gin continues to be the drink of choice among locals. Tomorrow we head to a spot in Istanbul where you can spend an evening visiting a number of bars, all without leaving the building. Spain is a country that loves a long-drink – alcohol in combination with a soft drink, refreshing and open to invention and reinvention. On the heels of creative gastronomy’s efflorescence in recent years, many old drinks, cuisines and forgotten ingredients have returned, revived through new and more sophisticated techniques and interpretations. The gin and tonic, called gintonic here, is one such Spanish obsession, and all that ingenuity and focus have gone into taking this highball to the next level.

Fried tortillas, stuffed and sauced: enchiladas are simple in concept, but they come in a seemingly endless variety, depending on region and ingredients. The tortillas might be made of corn or wheat flour, and they could be stuffed with all manner of meat or vegetables (or both), but the sauce – or salsa – is really what it all comes down to.

“I’m not a missionary, but I am not doing this just to make a profit. People must see that there is mantı outside of Kayseri, there’s Crimean Tatar mantı, as well,” explained Gülben Resuloğlu, in front of her restaurant in the leafy Feneryolu district of Istanbul’s Asian Side.If Martha Stewart were in the mantı (also known as “Turkish ravioli”) business, her place would look just like Gülbi’s – meticulously decorated in pastels, white and floral prints. Everything matched, even the two neatly dressed women who welcomed us: Gülben (the Gülbi in question) and her sister, Leyla. But kept just behind tidy appearances, we discovered, is the pain of being Tatar. We’re convinced that this identity, which was forged in the fire of dispersal and diaspora, made the food taste better.
