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.

A proper way to start one's day is with a fresh cup of black tea from the wonderful tea master Bayram in Karaköy's 16th-century Kurşunlu Han building. It's the first stop on our Two Markets, Two Continents walk.

We were sitting at the counter, trying out the goods, when an elderly man who has clearly had a tough life copped a squat at the next bench. Leaning on a crutch, with only one eye and a very dinged-up forehead, he patted our shoulder to offer us a cup and a pitcher of fresh, cool water. We chatted a bit. Telling us he’s a regular and praising the preparation of the veggies at El Comunitario, he flashed his toothless, but endearing, smile, “What do you think of how much people are paid here?” It was a genuinely pleasant immersion into the social whirl of this community kitchen, located in one of the more troubled corners in the heart of Mexico City’s Centro. We began to pour water into our other neighbors’ cups and chatted with the cooks in the kitchen, enjoying some great, incredibly cheap grub.

In order to fully appreciate Tokyo and its deep food scene it’s necessary to not only peek behind the curtain of yesterday, but also join the constant flow of people eating their way through the city of today and even tomorrow. Our Tokyo walk will allow us to do just that, taking us on a journey that serves as an edible survey of the city’s culinary past, present and future.

Three humble ingredients – potato, cabbage and bacon – that’s all it takes to cook trinxat, the quintessential Catalan wintertime comfort dish. Potatoes and cabbage are boiled and mixed with fried bacon, and everything is cooked as a mash in a pan until it resembles a potato omelet. Its simple ingredients and even simpler preparation are exactly what make this dish so delicious.

A wide variety of reasonably priced fresh fish, shellfish, crabs and kalamari for the customers to choose at the Athens Municipal Market, a stop on our Culinary Secrets of Downtown Athens walk.
