The rustic Neapolitan tarallo, made of 'nzogna (lard), pepper and toasted almonds, is a true delicacy. It can be considered the first popular snack in Naples, a bite that combines the punch of black pepper with the sweetness of almonds, the whole united by lard. It’s a dangerous combination for the waistline, that’s for sure. Taralli are offered to celebrate a new home, shared with friends during soccer matches, enjoyed with one’s significant other on the rocky shore, given to guests at parties, taken aboard boats (it’s the very height of yuppiness to eat them accompanied by iced spumante while out at sea). Until a few years ago, taralli were sold by tarallers, roving vendors who carried a basket full of taralli on their heads.

Back at Culinary Backstreets Istanbul headquarters in 2012, every once in a while a conversation would arise about how çiğ köfte had emerged as a sort of fast-food franchising opportunity, with young entrepreneurial types starting up these meat-free meatball joints in all sorts of Istanbul neighborhoods. We all agreed it was much cooler than opening a KFC or an Orange Julius in the food court (though the former has been making its mark across the shopping malls of Turkey for a while now), and we were happy to see the ambitious souls of Turkey setting their sights on the bulgur meatball stand instead. The bespoke lokma shops and waffle bars may come and go, but çiğ köfte has its forever fans of all generations – and a new clientele now that it has caught on to its vegan marketing potential.

It wasn’t very long ago that finding a vegan restaurant in Mexico City was like finding a friend on the city’s overcrowded metro during rush hour (read: impossible). In fact, until this decade there were no exclusively vegan eateries in Mexico’s bustling capital. This is not to suggest that vegan options weren’t available, but exploring the city as a vegan could be a tricky business, and veganism was a little-understood concept. So unusual an idea it was, that journalist-cum-chef Mariana Blanco was often called a loser or perdedora by friends who found her animal-free and plant-rich lifestyle to be at odds with what they knew. So when she opened the first vegan restaurant in the city, and indeed the first in Latin America, she called it Los Loosers.

We bit into the khinkali, its handmade dough indelicate and sticky, as we like it. Steam poured out the newly made hole, and we blew lightly before slurping up the rich stock and gobbling the dumpling down, even the puckered knob. The ground pork and beef was packed with fresh cilantro, the juices absorbed into the jacket. It was a perfect khinkali. A home wrecker. This seducer of a dumpling is molded by the knowing hands of Manana Osapashvili, born in Gudamakhari, a mountain village in Pasanauri, the heartland of khinkali. A professional cook for 29 years, Manana has been making khinkali since she was 10 years old. Today, she is running the kitchen at Sioni 13, located at the Tbilisi Theological Seminary in Old Town. It is a part of the city known for its tourists and hookah bars, and the mediocre "traditionnel" Georgian restaurants that cater to them.

For a century and a half, the building housing Guixot has taken on many personalities – though one thing has remained the same: It’s always housed some type of bar that also served food. Now a tapas bar celebrated for its sandwiches, brothers, partners and cheery owners Francisco and José Gutiérrez Murillo have been running the iconic eatery in the Raval neighborhood since 1986. Here we can find some of the more interesting sandwiches of the Old City, along with good tapas and a lunch menu of daily specials. Exuding a relaxed, familiar and friendly atmosphere, the space still keeps an old school look with its marble tables and thin iron columns from the past century dotting the interior. It makes good use of its walls, exhibiting paintings that seem to recall its previous life – and it’s had many.

The downright whimsy of Filomila is hard to ignore – or resist. Perhaps it is the red exterior with the French-inspired script or the vintage bric-a brac and posters that cover the walls. Or it could very well be the sight of all the pies, sitting patiently by the window just asking to be eaten. One thing is sure, most of the shop’s allure stems from the energy of its owner, Efstathia, who four years ago decided to go rogue after working in various Athens restaurants and open up with just 3,000 euros to her name, against all advice from friends and family.

We are in the Vasto district, a difficult to navigate maze of narrow streets that criss and cross, a market area squashed between Naples’ central station and Centro Direzionale, the business district. The district’s Via Nazionale, a street adjacent to the station, is a shrine to local gastronomic treasures, and we consider it a true paradise for lovers of good food. It’s a jewelry box of flavors, ideas, and unique and original products. The daily street market on Via Ferrara, another local artery, is one of the city’s most colorful and fascinating – mentioned several times in renowned author Elena Ferrante’s “My Brilliant Rriend.” It was here, in 2016, that Dario Troise brought to life a project 15 years, if not centuries, in the making: a panini bar that serves only cuzzetiello (which roughly translates to bread bowl sandwiches).

Nowhere in Mexico City does one feel the collective weight of the largest population in North America more than on Avenida Lazaro Cardenas, the traffic artery that gushes a surfeit of humans and cars up the heart of the city’s downtown. The gutters stink of rotting fruit. Dirt and littered garbage encrust the sidewalks. And, at rush hour, walking a block means suffering a gauntlet of elbows and hands pushing at you and past you. For the most part, the businesses that line this street offer little comfort. Goods lie in heaps on carpets or hang two feet deep upon the walls of stores seemingly designed to be fire hazards, cramming too many people onto too little floor space.

The first few blocks of Baruthane are lined with a smattering of restaurants, barbers, television repair shops and dry cleaners, though in recent years a flurry of third-wave coffee shops and bars has arrived on the street. While this is a positive development for the young adults that patronize these establishments, there is the inevitable concern that their proliferation will cause a spike in rents and tarnish the quaint character of this beloved neighborhood. It is for this reason that we were thrilled to see a new establishment open up on Baruthane that reflects the classic small-business character that makes this area so special. Köy Börek is run by Abdullah Kral, a cheerful 53-year-old teddy bear of a man who makes some of the most delicious börek we’ve ever had – and we’ve had a lot. (Kral means king in Turkish, and we are prepared to crown Abdullah bey the king of börek.)

Speed down the National Road till you’re in sight of Rendis Market, then follow the trucks off the highway and into a vast depot of concrete sheds. Though the trucks are there to pick up and deliver fruits and veg from all over Greece to supermarkets, grocers’ and farmers’ markets, we pulled over and started shop-hopping. Rendis, an industrial district of small factories, warehouses and train yards on the west side of Athens, has never been an area one would go for pleasure.

Addy has cornered the Astoria market in Kenyan cuisine. Even so, large portions of his menu are devoted to dishes familiar all around the world, and popular with all ages. They include a dozen or so flavors of chicken wings and a fistful of burgers, some basic, some overloaded. (Lean forward over the plate, is our advice, when biting into a Juicy Lucy.) To our surprise, the American South stakes a claim at Addy's after all: The country-fried steak, served atop mashed potatoes and accompanied by a brimming cup of gravy, is one of the best we've ever had. Because mishkaki is new, at first, to most of Addy's clientele, he's simplified the presentation rather than risk confusing his customers. Typically, at a Kenyan roadside stall, mishkaki is served with flatbread, the meat arrives on the skewer, and the customer adds sauces and other accompaniments to his or her liking. In Astoria, mishkaki is served with rice and a salad, and the chunks of meat, sans skewers, are already seasoned, à la Addy. We can practically taste the sizzle.

Naples is a city strewn with street vendors. Bread, thin pizzas meant to be eaten folded, fried pizzas, octopus broth, roasted artichokes, cones full of fried goodies, donuts, panzerotti and rice balls – there’s little you can’t find one of Naples’ vendors selling. Together, these numerous street sellers and their small stands play an important economic and cultural role in the city. In the midst of all these vendors there’s one that somehow manages to stand out. Some know him simply as Carmine. Others call him Carmine the Wizard because of his enchanting roasted chestnuts, which warm the hands and the stomachs of Neapolitans in winter. Whatever you call him, he’s an icon of Naples street food.
