Carmen and Eduardo’s story could be an allegory for the rise and uh-oh moment of Brazil’s new middle class – except their tale is a real one, one that ends with a really nice savory fried pastel that’s become a midnight munchie hit with their neighbors in Rio’s iconic City of God (Cidade de Deus) favela. The pair’s life together started early; they met when Carmen, now 30, was just 12 years old; moved in together when she was 14; and both converted to evangelical Christianity and married in a church when she was 18. They came to the City of God, well-known from the book and film of the same name, looking for a more economical housing option.

In 1654, Dutch refugees, including 23 Jews, traveling on a French ship from Brazil, arrived in North America. The refugees set foot in Peter Stuyvesant’s New Amsterdam village, now called New York. Stuyvesant did not want to accept Jews, so he imposed trade, property and tax restrictions to stifle their advancement. Most of the Jewish community consequently returned to Amsterdam or left for the Caribbean, where they could live under more hospitable conditions with relatives. When Stuyvesant ultimately ceded control of New Amsterdam to the English, the small Jewish community that had remained swore allegiance to its new rulers and began to grow.

“People know about our peas all over the world!” Marc Bertrán exclaimed as he stood, arms crossed, behind a folding table laden with jars of cooked green peas, stacks of pamphlets and a big crock of silky pea hummus with a bowl of crackers, inviting passersby to enjoy a taste of three generations’ worth of dedication. “In the 1950s,” Bertran told us proudly, “our town’s famous dish, Pèsols ofegats a l’estil de Llavaneres” – Peas stewed in the style of Llavaneres – “was featured on the menu at Maxim’s restaurant in Paris.”

The popular saying that Rio is known more for its bar culture than for its café culture has serious counter-evidence in the old city. Beginning in 1808, when Portuguese emperor Dom João fled Napoleon and relocated his imperial court to Rio, European architects, businessmen and intellectuals followed him and attempted to show that their society could thrive in a tropical land. Many stayed on after the royal family returned to Portugal in 1822, and over the course of the 19th century filled the old city’s cobblestone streets with neoclassical row houses, Baroque revival churches and a Beaux-Arts theater. Into this mix, Frenchman Charles Cavé founded a bakery in 1860 in a pink Victorian building as frosted in white trim as the pastries it purveyed.

It was Mr. Liu’s huge grin that first caught our eye, welcoming us into his humble, living room-sized restaurant. Scanning the small space, we suspected we had hit upon a gem: white tile walls, basic stools, vegetables crammed into the fridges in the dining room and fiery red dishes dotting the tables of happy diners – all hallmarks of the down-to-earth eateries we’re always looking for. As we sat down and he started explaining his specialties, we could feel his genuine interest in having us taste his authentic Sichuanese cuisine, going well beyond just making another sale.

“It is betrayal,” As’ad Salloura declared from behind his giant wooden desk at the Salloura factory, tucked away on the outskirts of Istanbul. From here, he runs the transplanted 150-year-old sweets empire that is his family’s namesake. It had been three months since he’d last seen Ahmed, his most cherished employee, Rashed, another integral part of the staff, and two others. “No one told me they were leaving…I found out by chance maybe four or five hours before they left [for Europe],” he said, his thick dimpled fingers thumping the table as he spoke between sips of cigarettes and mate, an herbal caffeinated tea popular in Syria.

They weren’t easy to spot at first: tiny green shoots with reddish roots, scarcely an inch high, poking out of the mud along the banks of a brackish stream near the Aegean town of Alaçatı. From these unpromising beginnings come a dish known to nearly every patron of a Turkish meyhane: nutrient-rich deniz börülcesi (samphire), typically served boiled and dressed with olive oil, lemon, and garlic. The simple word ot, which translates to “herb” or “weed,” doesn’t do justice to the important – and delicious – role these wild greens play in the cuisine of Turkey’s Aegean region. Though most commonly served as zeytinyağlılar, dishes “with olive oil” like the classic deniz börülcesi salad, their versatility was on full display at the recent Alaçatı Ot Festivali, an annual celebration of all things leafy and green.

Wild greens or horta (χόρτα) are an ancient and still very important ingredient in traditional Greek cuisine (and happen to have exceptional nutritional value to boot). Every season brings different varieties: some more bitter, some milder and sweeter, some naturally salty, all with different textures and shades of green. Almost every single taverna around Greece includes horta in the salad section of the menu. These boiled greens served with virgin olive oil, sea salt and plenty of freshly squeezed lemon juice are one of the most common salads enjoyed throughout the year, usually with fish, but sometimes also with meat. When eating out, Greeks typically ask the waiter what type of horta the restaurant serves, as they know it depends on season, region and availability of each variety.

Anyone with observant eyes and a rumbling stomach will notice how newcomers to the city – and their snack foods – are cropping up like the pink beijo-turco flowers that grow in Rio’s forests after a heavy rain. There’s Hasan with his eggplant esfiha pastries amongst the popcorn vendors and candle-lighters at the Nossa Senhora da Glória church of Largo do Machado; energetic and trendy Armin with his falafel in Botafogo; tired Hafez with his boxes of savory snacks, trying to find shade on the Rua das Laranjeiras. Brazilians didn’t need to be told to like Arab food, and now they’re getting a fresh wave of that culture’s already iconic snacks. The bready esfihas and bulgur wheat kibe may be to Brazilians what chicken tikka masala is to Brits, a formerly foreign food now amongst the country’s most ubiquitous for drunk munchers and rushed lunch-breakers alike. Arab migration dates back over a century in Latin America, and Brazil’s Lebanese diaspora is the largest in the world, with a population as high as 10 million. Some 10 percent of Brazil’s congress is of Arab ancestry.

In the heart of Alfama’s historic flea market is a surprise: Lisbon has a small restaurant dedicated entirely to mushrooms. Located inside the charming old market building from where there is an excellent view over the Tagus river, Santa Clara dos Cogumelos (Saint Clara of Mushrooms) is a very peculiar eatery: from starter to finish, including desserts, are unexpected combinations of shiitake, oyster, porcini, black trumpets or truffles, all cooked using a variety of techniques.

Turkish Cypriot Hülya Çavuşoğlu had always been a good cook but had never thought about making it her profession. That changed in 1995 when, looking for a change, she quit her job in a government office and started a business making and delivering home-cooked food, specializing in mantı, a dumpling found throughout the Turkic world, and börek, stuffed pockets of dough. Business boomed, her husband Ahmed gave up his job as a tailor to do front-of-the-house and they moved to a tiny shop with four tables, naming it Hamur, which means “dough” in Turkish. Located just outside the old walls of Lefkosa, the slice of Cyprus’s capital located in the breakaway northern part of the island, it’s a remarkable little restaurant, serving the freshest of hand-made mantı and börek to everyone from students to diplomats trying to negotiate a settlement between north and south.

Architectural and historical monuments of the Ottoman Era, the hans and caravansaray that freckle the old city, have mostly been left to their own devices. Originally built as imposing weigh stations for incoming traders, today they are crumbling in places and patched up with duct tape in others. These buildings are still living spaces of commerce and craftsmanship, or simply storage, a tradition which reaches back centuries. Wandering around one han which hosts a bustling trade in yarn, or visiting an Armenian silversmith in his tiny vaulted cell tapping detail into an elaborate dinner plate is a magical experience.

It was a hot, humid June in Istanbul. A deadline hovered over Ahmed. He gave himself three months to make the biggest decision of his life: Would he stay? Or would he go? The reasons to leave Istanbul far outnumbered the ones to stay. He was working day and night for a salary that barely made ends meet. The long hours weren’t new – his life in Aleppo was work, 15 hours a day, seven days a week. But unlike in Turkey, Ahmed made more than enough in Syria: he bought a brand new house for his family just before the war; his wife, Laila, was a respected housewife, pushing her kids to study; his two older kids, Rubi and Ruseel – little Rivana wasn’t even born yet – went to good schools. Rubi even had a private English tutor.

We consider ourselves fabulously lucky every time we snatch up one of the ten counter stools or the three-seater table inside the triangular shaped and miniscule Savoy Pizza. Up a few steps as the street curves around behind itself, this smallest of small restaurants is easily missed; the space seems carved out of the corner of a building, almost like the bow of a ship. The best way to find it is to look for the clutch of hungry people hanging around outside, waiting for their slice of Neapolitan-style heaven. It is the kind of place that one is told about and then hesitates to tell more people lest the line outside never end.

In Shanghai, wet markets hold the telltale signs that spring is finally upon us. Stalks of asparagus as thick as a thumb spring up first, alongside brown and white bamboo shoots so freshly pulled from the earth that dirt still clings to their fibrous shells. But the most exciting spring green is fava beans (蚕豆, cándòu), also known as broad beans. Their short season in Shanghai – usually just about four to five weeks – means they’re in high demand, and stalls are filled with workers shelling the labor-intensive beans by the bushel.
