There’s an old Catalan saying that goes, A Vic, llonganisses, frares i misses (“In Vic, cured sausages, friars and masses”). The capital of the Osona region – equidistant between Barcelona and the Pyrenees – was indeed for a long time an important religious town: it is said to be one of the towns with the highest number of convents and churches in Catalonia. Nowadays, university students and a diverse off-campus population have largely replaced priests and nuns, while masses have been swapped for music, film and other cultural festivals. Cured sausages, though, have managed to retain their place in local culture and are in evidence in every single pork deli shop window in this central Catalonia town.

We were sitting at the counter, trying out the goods, when an elderly man who has clearly had a tough life copped a squat at the next bench. Leaning on a crutch, with only one eye and a very dinged-up forehead, he patted our shoulder to offer us a cup and a pitcher of fresh, cool water. We chatted a bit. Telling us he’s a regular and praising the preparation of the veggies at El Comunitario, he flashed his toothless, but endearing, smile, “What do you think of how much people are paid here?” It was a genuinely pleasant immersion into the social whirl of this community kitchen, located in one of the more troubled corners in the heart of Mexico City’s Centro. We began to pour water into our other neighbors’ cups and chatted with the cooks in the kitchen, enjoying some great, incredibly cheap grub.

In order to fully appreciate Tokyo and its deep food scene it’s necessary to not only peek behind the curtain of yesterday, but also join the constant flow of people eating their way through the city of today and even tomorrow. Our Tokyo walk will allow us to do just that, taking us on a journey that serves as an edible survey of the city’s culinary past, present and future.

In the era of such food crazes as the “cronut,” it seems that every city has its own classic fried-dough treat that is now being reimagined, and in Athens, loukoumades (think of them as the Greek predecessor of doughnut holes) seem to be getting a major overhaul as of late. Why revamp such a perfect childhood classic, you might ask? Loukoumades are considered to be one of the oldest recorded pastries (and desserts, for that matter) in the world – in fact, the ancient Greek poet Callimachus and philosopher Aristotle wrote about these bite-sized, fluffy fried-dough balls. The triumphant winners of the first Olympic games in ancient Greece were the ceremonious recipients of xarisioi plakoi (χαρίσιοι πλάκοι), or honey gift-cakes.

Bāozi (包子), or steamed buns, are a basic, on-the-go meal. It’s rare to come across a shop selling these buns for more than 1.5 RMB (US$0.25), and yet, the past five years have seen a dramatic rise in the stature of this humble dish – thanks mostly to celebrity chef David Chang, whose Momofuku pork bun has become world-famous. They even got a domestic boost in 2013, when President Xi Jinping visited a local 60-year-old baozi shop in Beijing. (Now, thanks to an hours-long queue to try the “President Special,” that chain is looking to go public.) Legend has it that baozi date back to the Three Kingdoms period (A.D. 220-280) and are credited to Zhuge Liang, a renowned military strategist who was also an eccentric foodie. He invented both this steamed bun and our favorite breakfast treat: the jianbing

For years, expats in Shanghai complained about the lack of quality desserts in the city. Perhaps they just meant familiar desserts, as locals were more than happy to point them to delicious egg tarts, mooncakes or Taiwanese iced treats. But alas, when it came to sweets, there seemed to be a Great Wall-sized divide between East and West. In an effort to bring together sweet tooths from both sides of the dessert dividing line, in 2010 Lexie Comstock started Strictly Cookies, an American-style cookie delivery company in Shanghai that she hoped would delight expats and win over locals along the way. Having first visited China in 2000 while in middle school, Comstock later plunged into studying Mandarin and majoring in East Asian Studies at Harvard.

Dear Culinary Backstreets, I’ve heard about “wet markets,” but what are they exactly? And where can I find the best wet markets in Shanghai? Stocked with all the fresh produce and live seafood that hungry Shanghai residents could ever cook up, wet markets are an essential alternative to the brand-name supermarkets vying for their slice of the market share of the planet’s largest population. These markets are so named because the floor tends to be wet, thanks to the live fish flopping around and the vendors’ habit of throwing water on the ground to keep the area clean. They are, however, under constant pressure from the central government’s drive to urbanize the population and modernize facilities, which has led to the steady destruction of the more traditional ones.

Shanghai’s farm country is closer than most residents imagine, especially when surrounded by the city’s seemingly endless forest of skyscrapers. But just beyond the spires is a huge, green oasis: Chongming. Somewhat smaller than Hawaii’s Kauai, this island at the mouth of the Yangtze River grows much of the municipality’s food supply. The government is pushing plans forward to develop the area with “eco-friendly” industries by 2020 but, as usual, has not provided many details on how these goals will be achieved. A stopping point for millions of migratory birds each year, the island (for now) has several wetland zones and ecological parks that are open to visitors, making it a worthwhile jaunt for those wanting to escape Shanghai’s urban jungle.

Dear Culinary Backstreets, I’ve heard about drinks in Mexico called “aguas frescas,” but what exactly are they? Visitors to Mexico are sure to encounter aguas frescas, a popular category of drinks that are ubiquitous at food stands and eateries around the country. These colorful beverages, whose name literally means “fresh waters,” come in a variety of different flavors depending on the main ingredient, but generally all are made by mixing a fruit juice with water and sugar.

One of the seven necessities of Chinese daily life, rice is eaten in many forms throughout the day, including – and especially – at breakfast. Congee is undoubtedly China’s best-known breakfast food, but less famous globally, and wildly popular locally, is the unassuming rice ball (饭团, fàn tuán).

Chalkida, the small peninsula on central Evia (Euboea) just an hour’s drive from Athens, is an ideal day-trip destination for urbanites. It’s famous for an unusual phenomenon, in which the tide in the Strait of Evripos changes direction several times a day, and it’s also known among tourists for its fresh and delicious fish and seafood. When Chalkideans want fresh seafood, however, they head to the less touristed town of Nea Artaki, just north of Evia’s main city. In the tiny port, there’s a classic promenade lined with taverns, and the penultimate, Teskos, is our favorite destination. On a recent visit, the weather was beautiful, sunny and cool enough for us to sit on the sidewalk adjacent to the sea.

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.

[Editor's note: We're sorry to report that Harbin Dumplings has closed.] Walk along just about any street in Shanghai these days, and you’ll see an ever-encroaching range of Western brands, standardized brand signage and food franchises. As in other rapidly developing countries, the battle for consumer dollars and brand loyalty has meant more chains and mass-produced food. That’s partly what makes stepping into one of the several Liu Family Harbin Dumplings shops a breath of fresh air. Every morning until the lunch rush, the dining room and back rooms are set up with trays and workers dexterously making every dumpling from start to finish. Dumpling wrappers are meticulously hand-rolled, the fillings are mixed in large batches, and the time-consuming process of filling and closing the dumplings marches on until tray upon tray is ready for boiling – but not until they’re ordered during the lunch rush.

Who says there’s no such thing as a free lunch? In fact, over at Gastronomika, a new Istanbul culinary project, the food is served not only free of charge but also with an intriguing – and ambitious – backstory

Strict vegetarians in Shanghai face a double-edged sword when it comes to staying meat-free. On the one hand, the country’s large Buddhist population means they are in good company. It is estimated that the total number of vegetarians in China reached about 50 million last year. However, while tofu dishes can be found on just about every Chinese menu, that doesn’t mean that the dishes are strictly meat-free. To vegetarians’ dismay, pork and meat-based broths are often used to give the soy-based dishes more flavor, and special requests (even simple ones like “no meat”) are not usually complied with (or understood). Traditionally, meat is often sliced in very thin strips (肉丝, ròu sī) and used to flavor vegetable and tofu dishes, as opposed to being the star
