Since the late 18th century, this quiet street corner in the salty seaside neighborhood of La Barceloneta has borne the name Can Solé. The long history of this tradition-steeped restaurant began with Gregorio Solé, owner of a shop of the same name, which sold soaps, oils and other sundries. In 1903, the space was sold to Josep Homs, who kept the name above the door and converted the shop into a restaurant, setting in motion a 113-year trajectory – from fisherman's tavern of humble stature to famous culinary institution, offering some of the best classic Catalan cooking, rice dishes and seafood in Barcelona.

In the Laz language, “si sore” means, “where are you?” At least twice a week for past few years, our answer to that question at lunchtime would be, “We are at Pera Sisore.” This little restaurant in the Asmalımescit area became one of our go-to lunch spots by serving some of the best Black Sea food around town. But after a disagreement, the two partners of the restaurant went their separate ways and the quality at Pera Sisore, sadly, took a turn for the worse. We were feeling a bit lost for a period, not knowing where to go for a quick, honest lunch of hearty Laz fare. The Black Sea area is Turkey’s culinary misfit – it's not really about kebabs or mezes. If anything, the food there seems to have been mysteriously transplanted from the American Deep South.

It’s a buzzing Thursday night at Associação Renovar a Mouraria (ARM), a one-room bar and eatery found in a nook at the top of some ancient stone steps leading up from Rua da Madalena. Dani, a local tattooist born in Java, is cooking for around 35 people as part of the weekly Jantar Cruzado (“dinner crossing”), an initiative aimed to improve social inclusion in this old part of town through the simple act of making food.

So you’ve eaten your way around Shanghai’s delicious noodle shops and restaurants but want to bring a taste of China back home? Or maybe you’re searching for a weird food gift (pickled chicken feet anyone?) for a hard-to-please friend. You’re in luck, as specialty food shops dot the city and are quite popular with locals, offering a huge variety of well-packaged items.

In the Istanbul neighborhood of Kurtuluş, home to a large Armenian population, a number of shops are decorated on account of Easter, and the smell of traditional sakızlı Paskalya çöreği--puffy loaves of ever-so-slightly sweet bread baked with mastic gum--is thick in the air.

Our monthly series on migrant kitchens in Queens, NY, told through interviews, photos, maps and short films, takes us next to stories about the migration African-Americans to the borough. In the accompanying video, we look at the fascinating history of The Green Book, which between the 1930's and 60's provided African American travelers with a guide to hotels, restaurants, taverns, road houses, gas stations and homes where they could be sure to have a place to eat and rest without the threat of violence.

Like many other cities in Europe, Lisbon’s burger trend has been growing strong, with gourmet versions and strange national adaptations overtaking the capital. But the bifana, Portugal’s quintessential hot sandwich, will always trump any trend for locals who want quick nourishment. Composed of a thin pork filet cooked in a sauce made from white wine, garlic, bay leaves, lemon and lard, the bifana is an irreplaceable cultural habit.

Fresh pomegranates await to be squeezed into juice near Istanbul's iconic Grand Bazaar .

Visiting the Jamaica plant and flower market is one of our favorite activities in Mexico City; we love getting lost in its green alleys and never fail to emerge with at least one new plant and a beautiful bouquet of flowers. And of course, we’re always on the lookout for new places to eat. Our favorite barbacoa joint is in this market, but when we want a different experience we head to the huarache alley, where several stalls offer this tasty Mexican specialty.

There used to be a state-owned publishing house in our neighborhood with a cafeteria that served a proletariat menu that included ostri (beef stew), cold slices of beef tongue and cutlets with buckwheat or mashed potatoes. It was a stolovaya, which is the Russian word for “canteen,” but a more accurate translation would be “human fueling station of protein, carbs and vodka.” It was gutted several years ago; its ghosts now haunt the dining room of a designer hotel.

Dear Culinary Backstreets, I’m on my way to Tokyo in the next few weeks and wanted to enjoy the cherry blossoms at a typical hanami celebration. Where can I find such a celebration, and what kind of food can I expect and where can I find one? We can fully understand why you want to partake of a hanami, or cherry blossom viewing party, as most Japanese people do. The ritual has been around for over a thousand years in Japan. Cherry blossoms – sakura – will bloom in lavish displays of wonderful pink magic all over Japan, starting on the southern island of Kyushu at the end of March and moving north to Hokkaido by the end of May.

Tucked away in an alley in Istanbul’s Aksaray neighborhood, Şirket Alahdab is a small grocery store overflowing with Syrian staples: pickled baby eggplants, dried leafy greens, cans of clotted cream for desserts. When we enter the store, Istanbul temporarily fades away and Damascus or Aleppo take its place. “All real,” the clerk declares proudly, as he shows off his goods. “Smuggled from Syria.”

As part of CB's "Usta All-Stars" card project, our intrepid researcher Ali Akas went around town interviewing street food vendors about their work, the food they serve and some of their trade secrets. Besides the cards, another result of Ali's work was this map, which plots the relative locations of some of Istanbul's finest vendors.

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.

All over Athens (not to mention the U.S. and other parts of the world), one of the hottest grains around is also among the oldest known to man. While farro, or zea, as it’s known in Greek, has been found in excavations of prehistoric settlements in parts of what was once Ancient Greece (the oldest, in Asia Minor, dating back to 12,000 BCE), in the early 20th century, its cultivation was banned, largely because it was cheaper to import other grains (though many incredible conspiracy theories behind the ban abound). Thankfully, zea began making a comeback about 15 years ago, and it is now popular again, not just in grain form, but also as flour for making baked goods and pasta.
