Dust, sweat, rain, and severe sun – these were only a few of the many discomforts that travelers of yore suffered as they made the long journey in horse-drawn carriages from their home provinces to Barcelona. In those days – around a century or two ago – the city was protected by fortified walls; it was outside of those walls, in an area known as Hostafrancs, part of the Santa Maria de Sants village (today the neighborhood of Sants), that many travelers and merchants found a convenient refuge – a place to recover from the journey. Taverna La Parra was one of the several inns that dotted the area.

We travel along Barcelona’s urban wine route on our Bodega walk, joining regulars who come in to fill a jug with wine straight from the large wooden barrels that line the walls and pause for a game of cards, a drink, a bite to eat and some banter.

It was a scorching summer day in Istanbul, one of those days when the only thing you can imagine eating is ice cream. We were in Moda, and our friend Vicente suggested a stop at Dondurmacı Yaşar Usta – in fact, he’d been raving about this ice cream all summer long. So we followed him to the branch on Bahariye Caddesi, in hopes of understanding why he’s so crazy about it. It didn’t take long for us to figure things out. The homey, no-frills atmosphere and the array of creative ice cream flavors make Dondurmacı Yaşar Usta something of an oasis in Moda, a hip neighborhood on Istanbul’s Asian side, where a majority of the new food ventures springing up like mushrooms prioritize a shiny cool look over substance.

While on our way to an unforgettable bite in the center of the main fishmongers’ market, these silvery beauties caught our eye. This is just one of the many backstreets we explore on our Culinary Secrets of Downtown Athens walk, as we go in search of the soul of this historic yet always vibrant city.

Search online for Shanghai’s best fried dumplings, and you’ll come up with hundreds of results extolling Yang’s Fried Dumplings. Though it was once just a humble shop sandwiched between the Bund and People’s Square, the online renown and ensuing crowds have propelled the brand into chain-store ubiquity, populating new malls and shopping streets with fervor. In essence, they’ve become the Starbucks of dumplings; you’re going to get a relatively consistent product, but come on, you can do so much better! Enter Yang Yang’s.

Tucked against the back wall of the Expendio de Maiz kitchen are three massive metal pots. Containing cloudy mixtures of corn kernels and limestone water, they seem to sit unattended, when in fact intermittent yet constant attention is being paid to their progress. What is happening is one of the most ancient and important processes birthed by Mesoamerica: nixtamalización. For a people whose main staple was corn, the discovery of nixtamalization was just as important as the domestication of corn itself. This process of mixing corn kernels in an alkaline solution not only loosens the husks of the corn kernels, making them easier to grind, but also provides all kinds of additional nutritional value.

We kick off our Porto walk with the city’s favorite pastry, the éclair filled with whipped cream. It is so popular, the éclair was officially registered as The Sweet of Porto. We pair ours with a strong coffee for a soilid start to the morning.

Wooden wine barrels with taps, shabby old furniture, noisy antiquated fridges, soda siphons from the 1960s… these are the building blocks of Barcelona’s classic bodegas. Formerly shops that sold bulk wine, liquor and ice, these bodegas survived the Spanish Civil War, social conflicts, food shortages, financial crises and, of course, modernity, with their essence intact, even if they morphed into bars or restaurants along the way. The most important element of a neighborhood bodega, however, is neither readily visible nor easily captured: it’s the place of importance these spots occupy in the lives and hearts of the local residents. They are the scene of innumerable childhood memories and infinite moments shared with other locals from the block, making them a dependable point of reference in time and space.

While wandering deep in the guts of the Deserter’s Bazaar, Tbilisi’s largest and oldest open-air marketplace, we stumbled upon the raffish wine section where men (mostly) drop by for a few toasts. Join our Old Market & Beyond walk to taste these authentic homemade wines and chacha – Georgia’s legendary take on grappa – for yourself.

Carla Santos is a busy woman. On the day we go to meet her, it is pouring rain in Porto and Adega Vila Meã, the restaurant she runs, is full. Carla doesn’t stop for a second: “One of those pork firecrackers with potatoes?” she asks a customer as she swings through the dining room. She’s not alone in this mad dash. Carla works the tables with her youngest daughter, while the oldest, who learned how to cook from her mother, mans the kitchen. Even Carla’s 7-year-old granddaughter helps out, clearing tables. “It costs nothing to start learning right now,” says grandma Carla, already certain that “we are moving Adega from one generation to the next.”

One of the problems for travelers with celiac disease is that they often can’t taste local gastronomic specialties. This is particularly true in Naples, a city famed for its pizza and pastries, such as the mythical babà; pastiera, the queen of Neapolitan sweets; and the ancient sfogliatella. Until about 20 years ago, it was very difficult for someone with celiac disease to eat in Naples; the number of restaurants equipped for gluten-free cooking could be counted on one hand, and they often had to resort to processed food products sold in pharmacies.

The five-star Pera Palace is undoubtedly Istanbul’s most iconic hotel, with its palatial rooms and suites named after the legendary guests that stayed there, such as Agatha Christie, Alfred Hitchcock, Jacqueline Kennedy Onassis and Ernest Hemingway. Practically synonymous with the Istanbul of a century ago, it is the subject of a lovely tome, "Midnight at the Pera Palace" by Charles King, that locates the hotel within the fantastically tumultuous years leading up to and following the establishment of the Turkish Republic. Though we admire the Pera Palace and cannot understate its importance to the city’s modern history, it is not our favorite Istanbul hotel. That honor is reserved for the Büyük Londra (Grand Hotel de Londres), located just a stone’s throw away on the opposite side of the stately Meşrutiyet Avenue.

If anything in recent history has bonded Spanish hearts, it was neither politics, language, flags nor even TV. It was the tortilla de patatas, the iconic potato omelet. In every house, bar and restaurant, the tortilla de patates is always treated with intimacy and respect, like some sort of communal great-great-grandmother. And in every Spanish city, you will find a list of the best kitchens offering this specialty. For Barcelona, one neighborhood temple devoted to the omelet is Les Truites, a small family restaurant in Sant Gervasi run by Joan Antoni Miró and his son Marc.

When we set out to create a foodie “holiday” this past April for jianbing, one of China’s most-loved street snacks, we didn’t know quite what to expect. Our aim with World Jianbing Day, which included giveaways and a social media campaign encouraging people to add their favorite jianbing spots in China and abroad to a crowd-sourced map, was to build awareness outside the typical jianbing consumer base. Locals who grew up with and already love the snack don’t need much reminding about the virtues of the perfectly balanced crepe from northern China. But everyone else? They need to know about the sweet, crunchy, pickled, spicy and salty elements all wrapped up in one convenient burrito-crepe-style to-go snack.

After the merriment of sakura cherry blossoms has faded, bringing with it the dreary Japanese rainy season, the hot, humid days of July and August follow shortly thereafter. When summer temperatures and the humidity reach a point of sticky and awful, Japanese people tend to change their diet so as to shake off natsubate, the physical fatigue of summer. In a country where the main religion is nature-worshipping Shinto, most people practice the custom of shun: celebrating nature’s cycles and each season’s profusion of food. Loosely translated, “shun” means the height of nature’s abundance. Each of Japan’s fruits, vegetables and also animal proteins has its own shun, and in the essential and enduring wisdom of Japanese cuisine, that has influenced the preparation of Japanese food for thousands of years.
