Milky, tart, viscous and slightly foamy. At first glance and sip, there’s little to explain why pulque – a mildly alcoholic drink made by fermenting the fresh sap of certain types of maguey, the same plant used for making mezcal – has remained a trusted companion to Mexican drinkers since Aztec times. Pulque, actually, has not only survived, but, after decades of losing ground to beer and soft drinks and their high-priced marketing campaigns, this workingman’s brew is making a comeback. New pulquerías are popping up in hip Mexico City neighborhoods and attracting a younger crowd while old pulquerías, which endured some lean times, are seeing an influx of new customers, who now sit side-by-side with older generations of loyal pulque drinkers. Nobody really seems to know why the previously unheralded nectar has been getting this much attention in the last few years, but several places around town have been capitalizing on this new trend with great success.

Editor's note: We're sorry to report that ENOA has closed. Situated by the sea in the marina of Agios Kosmas, ENOA is part of a truly strange neighborhood. There are a couple of nightclubs, some cottages and the enormous, badly lit rowing and sailing buildings that have been left to molder after the 2004 Olympics – but mostly the feeling is of an abandoned wasteland by the sea. The entrance to ENOA, an area club, is equally unimpressive: a number of trophies cramped behind a glass display followed by a cavernous dining room that, with its harsh, unflattering neon lights, resembles a hotel from 1960s rural Greece.

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.

Situated on a geographically blessed spot where the waters of the Black Sea and the Sea of Marmara meet, Istanbul has long been associated with fishing and, especially, the eating of fish. In culinary terms, after all, is there anything more iconic in Istanbul than eating a freshly grilled fish sandwich sold from one of the bobbing boats down by the Golden Horn?

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?

At first glance, Bodega Manolo seems like the usual wine shop/tapas bar that Barcelona does so well: a solid place to replenish our wine stocks from the barrels, quench our thirst with a cold caña or satisfy our hunger pangs with a vermut and a tapa or two of oil-drenched anchovies. None of which sound too shabby. However, we know to venture through to the rear, where, at dinnertime, the brilliant white tablecloths reveal the venue’s greater ambitions.

Tacos are everywhere in Mexico City, and though the options are many – chicken, al pastor, carnitas, carne asada – the basic ingredients tend to be the same wherever you go. That’s why, as we were walking the aisles of Tianguis La Raza on a Sunday morning, El Parrillón caught our attention.

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.

“You can eat these raw, efendim!” shouted Aziz Bey to a suspicious woman dressed in a headscarf of sharp geometric designs and a denim duster. “Don’t be scared!” he said, ripping the cap off of a raw kokulu cincire mushroom with his teeth and chewing it in an exaggerated, open-mouthed way to show that there were no tricks. “Mis gibi!” he said, using a phrase that is more frequently printed on laundry detergent bottles or uttered by mothers doting over infants. “Fragrant!” In Turkey, many people assign much of what happens throughout the day to kismet, or fate, but when eating wild mushrooms you might be tempting it. Every year, it seems, local papers report on someone’s demise by mushrooms, which explained why the woman in the duster was reluctant to finish the transaction.

Anouchka hails from Extremadura, land of jamón and some of Spain’s best dry-cured sausages. Julien is French and an expert on wine. Together, the husband and wife run La Perla de Oro (“The Gold Pearl”), a pint-sized former colmado (old-style grocery) just off Las Ramblas, where top-notch bocadillos, or baguette sandwiches, are just one of many attractions. Since opening in 1939, three generations at La Perla have supplied their Raval neighbors with cured sausages, cheeses, preserved foods, salted fish and dried legumes. They became known especially for their bocadillos.

Dear Culinary Backstreets, I’ve noticed that a dish called “moustalevria” pops up in shops all over Athens in the autumn months. What is it, and where can I get it?

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.

Legend has it that in 12th-century Priorat, in the region of Tarragona in southern Catalonia, there was a shepherd who dreamt every night of a ladder leaning against a pine tree. The ladder ascended from the valley all the way to heaven and angels climbed up and down, tending to their heavenly and earthly duties. Some Cistercian monks, upon hearing this story, took the vision as a divine message to build the monastery Scala Dei (“Ladder of God”) in that very spot. Those clever monks, noting the angels’ comings and goings, decided to become their wine suppliers and began cultivating grapes and making wine there.

Dimitris Kotsaris was more proselytizer than baker. Rather than a flour-dusted apron, this mild-mannered gentleman would wear elegant suits to meet with journalists, bearing two or three kilos of his famous whole-wheat bread as a gift. He was an ardent believer in the medicinal qualities of bread and preached widely that good bread promoted good health, once even taking his case to Harvard, where he delivered a talk about the role of well-made loaves in healthy diets. In 1981 Kotsaris opened Pnyka, the pulpit from which he spread his yeasty gospel, and gave the bakery the Greek name for the hill downtown where, in the golden years of Ancient Greece, Athenians gathered for the general assemblies that played such a formative part in the creation of democracy. It is quite fitting then that the first Pnyka shop opened in Syntagma (“Constitution”) Square. The bakery has since added two more shops in the city, in Exarchia and in Pagrati, the headquarters of the operation, and its following is such that last year a third was established in Vienna. Kotsaris passed away last year but his vision lives on through his son George, who has taken over the business.

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).
