Alex Montes and his business partner, Askari Mateos, have spent years fussing over their recipes for tlayudas: large, thin corn tortillas topped with various ingredients. So what is the secret to a great tlayuda? Montes thinks for a moment. “The asiento [the unrefined pork lard that covers the tortilla],” he finally says, “and the beans, always with avocado leaf.” “The great thing about a restaurant,” he continues, “[is that] you make the same dish over and over so you have endless chances to perfect it.” We’d say that Montes and Mateos have done just that – the Oaxacan food at Las Tlayudas, the duo’s restaurant in Colonia del Valle, is pretty much perfect.

When it comes to Chinese dumplings, fish is likely not the first filling that springs to mind. But that’s probably because you haven’t had the chance to try Liaoning province’s specialty: boiled mackerel dumplings. Dishes from Liaoning, which is located northeast of Beijing, fall under the regional umbrella of Dongbei (northeastern) cuisine. The staple grain up north is wheat and corn, with noodles, steamed breads and dumpling wrappers supplying most of the carbs in the local diet. The area wraps around the coastline of the Yellow Sea, bringing fresh seafood to the table, and its proximity to the Korean Peninsula means an abundance of pickled veggies.

There’s something so soothing about taking refuge in a simple restaurant in the middle of a tough work day. These temples of comfort food dot Barcelona streets, with their daily specials written on a flimsy piece of paper or a blackboard. Come midday, laborers of all kinds – from blue-collar workers to executives in suits and freelancers in jeans – stream in, relaxing their minds in front of a good homey dish, one that’s free of ornamentation. In Spain, lunch is usually the main meal of the day, and most companies break for this midday meal between 2 and 4 p.m. This pause allows for a moment of spontaneous team building or a small escape; most people return to their workplace with a renewed vigor.

The T1 tramway route passes by virtually all of Istanbul’s most well-known sights. Crossing the Galata Bridge and weaving through the Old City, the T1 practically rubs up against the Hagia Sophia, Topkapı Palace, the Grand Bazaar and other famous attractions, ensuring that most foreign visitors to the city will ride this tram within a five-stop radius. But after the T1 rumbles past the old city walls, it snakes its way northeast through a dense patch of working-class districts usually ignored by tourists. Dreary on the outside though they may look, many of these neighborhoods are laced with off-the-beaten-path charm and culinary delights hidden in plain view.

Rua Catalana is a very ancient road, a corner of Naples where time seems to stand still. Located next to the financial district and now squeezed by 19th-century buildings, it is curiously the only road in the city that, instead of the Italian “Via,” uses “Rua,” a distortion of the French “Rue.” In the mid-14th century, Queen Joanna I of Naples welcomed merchants from all over Europe to the city as part of her efforts to promote trade. She donated this area to the Catalans, and tinsmiths and junk dealers settled here. Even though 700 years have passed, a smattering of small copper and tin artisans continue to practice their craft on this street, now making artistic copper and tin objects for the increasing number of tourists roaming the city.

José Saudade e Silva always knew, deep down, that he wasn’t cut out for tedious office life. So one day in 2014, after studying marketing and working a 9-to-5 job in that same field, he bought a one-way ticket to Oslo, where he had some friends. He didn’t exactly know how he would make a living there, but one of those friends quickly got him a job working in the kitchen of a new fine-dining restaurant, even though José didn’t have any sort of professional cooking background. His only experience in the kitchen was being around his father, an excellent cook. “My father instilled in me a love for food from a young age. He does a great bacalhau à Brás [salt cod with potatoes and eggs], among other dishes,” says the 27-year-old.

On our “Song of the Sea” walk in Lisbon, we visit some of the city’s best cervejaria, no-frills seafood and beer halls, where we find prized shrimp from the northern coast, the best cod cakes, percebes (the goose barnacles that are harvested from the rocky coast of Portugal) and delicious local clams.

When Brenda Miranda and her partners started Chilakillers seven years ago, it was on a lark. They were freelancers – like so many young professionals in Mexico City – who needed some extra cash and thought, “Who doesn’t love chilaquiles?” The only problem? None of them had much experience in the kitchen. But the mother of Brenda’s ex agreed to give them her salsa secrets – verde, mole, refried beans with chipotle, and a super spicy version (to which they would later add an avocado salsa and a vegan salsa). Plus, while Brenda may not have cooked much growing up, she did know meat – her father worked as a butcher all through her childhood in Mexico City’s Obrera neighborhood.

While English speakers “bring home the bacon,” Spaniards “bring home the bread.” Indeed, bread plays a central role in Spanish and Catalan cuisine, acting almost as an essential ingredient in its own right, rather than simply playing the role of sidekick to other dishes. In Catalonia there are hundreds of bread varieties that are readily available, yet it is the rustic pa de pagès, “farm bread,” that is king. Take the iconic pa amb tomàquet, bread rubbed with tomato, olive oil and salt, used in sandwiches and as an accompaniment for tapas and meals. While all sorts of loaves can be used for this humble yet essential dish, afficionados consider pa de pagès to be the best.

Manuel Azevedo and Francisco Moreira, now both in their 70s, have been friends since childhood. Such a close connection has afforded them the trust and togetherness required to run O Buraco, the restaurant in Porto that the duo have presided over like generals for almost 50 years. In fact, it was right after completing his military service that Manuel, a native of Marco de Canaveses, a city within the greater Porto municipality, came to Porto proper in search of work. “I picked up the newspaper, saw the ad, applied and was hired as a waiter,” he tells us. On February 4, 1971, he entered O Buraco (“The Hole” for the first time; he hasn’t left since.

We grew up in a household where drinking soup directly from the bowl was frowned upon, done only surreptitiously when Mom was looking away or as an act of impish rebellion, a bold unshackling from the spoon and its torment. Yet it took little prodding from Isis Iturriaga, founder and proprietor of Sanadoras La Caldería, to lift our earthenware bowl with both hands to eager lips and down the last of our impeccable caldo de hongos (mushroom soup) in three great gulps. “You are in your home,” she reiterated as the chipotle-infused liquid began to spark our insides. This is her mantra for the place, a plinth at the core of her being.

The trick to cooking calçots, a special Catalan spring onion, is simple: a good charcoal grill. The heat from the glowing embers is crucial to creating the perfectly scorched exterior (the black outer skin is then peeled away, leaving the tender and juicy inner bulb). Fire and smoke – along with exceptionally fresh green onions – are really the only ingredients here. The popular ritual of the calçotada, in which families and friends gather together with the sole purpose of eating calçots, traditionally takes place between the months of November and April, the peak season of this special green onion. For particularly large celebrations, groups crowd around an open barbecue, with sarmientos, or vine shoots, creating the perfect flame to blister the onions just so.

Xiaolongbao first appeared around 1875, during the Ming Dynasty, in Nanxiang, a village on the northwestern outskirts of Shanghai. As the story goes, a vendor selling dry steamed buns decided to innovate due to stiff competition. Legend also suggests, however, that he copied the giant soupier dumplings from Nanjing. Whatever the case, there are several regional varieties of soup dumplings today, including Nanjing-style, which are actually called tāngbāo (汤包), literally meaning “soup bun,” and traditional Shanghainese xiǎolóngbāo, which have heartier wrappers that contain a larger pork meatball in a sweeter pork soup. Here are five of our favorite spots in Shanghai for soup dumplings of all strips.

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. The equivalent to the British bubble and squeak, trinxat means “chopped” or “shredded” in Catalan. The relatively high altitude of Andorra and the Catalan Pyrenees brought with it harsh winters, food shortages and long periods of isolation, so in the past, people living in the region had to come up with a recipe that could help them cope with the adverse conditions.

Manuela, like many Neapolitans who emigrated abroad, used to make periodic trips home to see her family. On one such trip in 2012, she went to her grandmother’s house for Sunday dinner. As one does in Naples when a relative returns to the ancestral home, her grandmother prepared a ragù sauce for her. It was a simple meal, but one that would forever change Manuela’s life. When she finished eating, Manuela made the ceremonial scarpetta (dipping bread in the remaining sauce). Then a flash of inspiration came to her. “I thought, ‘Why isn’t there a place where you can eat only meat sauce? Where you can do the scarpetta like at home?’” she tells us.
