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.

It wasn’t so long ago that no one would venture to Georgia’s Svaneti region without a personal invitation, and even that was risky. Isolated, sky-high in the Caucasus, nestled between the breakaway territory of Abkhazia and the Russian Federation, it was land of the lost, inhabited by a tribe speaking their own language, living in hamlets dominated by tall medieval stone towers used for protection from invading hordes as well as from each other. Ancient pagan-Christian rituals, bride-napping, blood vendettas and banditry defined modern Svaneti – at least when viewed from the outside. We had heard too many stories of how oblivious tourists would wander there with cameras around their necks and big tourist grins only to return in their underwear with their heads hanging low. Like Georgians from the rest of the country, we stayed away.

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.

Spicy rabbit’s head is the ultimate bar snack in Sichuan province. The demand for rabbit’s head is so high in Chengdu that 20 percent are imported from Europe (mostly France and Italy). We crack open rabbit’s head (the cheek and the brain are the best meat) and pair it with a frosty bottle of Snow Pijiu beer on our Shanghai night eats walk.

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.

“I’m a vegetarian – what will I eat in Mexico other than beans and rice?” Taco-madness has so consumed the world’s view of Mexican cuisine that the traditional mainstays of the diet often don’t get the billing they deserve. Beans, corn, squash, chilies and tomatoes are grown together in milpa farms – a biodynamic system of agriculture. Anyone who has ever grown anything knows: if you let a garden grow naturally, you’ll have an abundance of leafy greens that most of us call “weeds.” Well, in Mexico, nothing edible goes to waste. Just as every bit of meat from an animal is used, so are those weeds and all the other tender leafy bits.

The typical Neapolitan breakfast is fast, often consumed standing at the espresso bar. A croissant and a quick coffee – and, boom, the day begins. Many people in the English-speaking world, however, will use coffee bars and cafès as a place to relax or work. They bring computers, connect to the Wi-Fi and, ordering just one coffee, may even sit for hours. Three years ago, a group of entrepreneurs decided it was time Naples had a bar where people could indulge in a lazy morning breakfast, a slow midday meal or a long afternoon tea – a place where the chairs are comfortable, the tables are an inviting wood and you are encouraged to stay and make your phone calls, write your papers and chat with friends.

A neighborhood on the southeast side of Filopappou Hill, between Acropolis, Petralona, Kallithea and Neos Kosmos, Koukaki was named after one of its first residents, Georgios Koukakis, who in the early 20th century opened a successful factory there manufacturing iron beds. Gradually the area developed into a charming middle-class neighborhood, full of life and – up until the 1980s – a place Athenians charmingly referred to as “Little Paris,” in large part because of its bohemian vibe. The lower side of Koukaki has long been a students’ area due to the nearby Panteion University. Rents used to be relatively low, but after the opening of the new Acropolis Museum in 2009, the surrounding area has been booming, growing into an Airbnb goldmine and turning many locals against the trend.

On our Naples walk, we stop at one of the city’s storied “water banks” for a taste of the Neapolitan gazosa, a relatively simple concoction made of lemon juice, bicarbonate and sulfur water. The digestive power of this drink is extraordinary – it’s perfect if you went overboard with pasta or pizza (or both), or woke up with a killer hangover. 

The Algarve, one of the most visited regions in Portugal, also has some of the country’s most distinctive and delicious cooking. Integrating layers of different historical influences, from the Romans to the Moors, along with fishing traditions and countryside rusticity powered by its fertile land, the Algarve has made a deep impression on Portugal. But until Taberna Albricoque came on the scene, the region hadn’t been making much of an impact on Lisbon menus. Bringing the Algarve’s history to the forefront of Lisbon dining was one of the goals of chef Bertílio Gomes in opening his new restaurant. Albricoque, in fact, is the word for apricot in the Algarve, notable because the south has preserved its Arab etymology, as elsewhere in the country damasco is used (instead associating the fruit with the city of Damascus).

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.
