The eyes of Tacacá do Norte’s harried staff widen as yet another customer arrives during the lunchtime rush. The bedroom-sized snack bar can barely hold one line of chairs around its bar but they have somehow managed to squeeze in two. Impatient regulars shake hands and whistle “psst” to the young men staffing the establishment, who gingerly hand steaming pots of shrimp soup and freshly puréed juices over the packed bar.

Pozole, like the tortilla, is one of those ancient dishes that seem to be embedded in Mexicans’ DNA, serving as a culinary link to the ancestral past. A type of soup or stew that was a ceremonial dish in pre-Hispanic Mexico, pozole has yet to be widely commercialized, offered mainly in pozolerías, small restaurants that specialize in serving up the dish and little else.

From the point in 2002 when multibillionaire Carlos Slim inked a deal with Mexico City to revitalize its historic center until now, there have been layers of change. Streets were made pedestrian-only after months of work by bulldozers and jackhammers. Broken windows and abandoned buildings have been replaced with countless new shop fronts offering shiny opportunities. Despite the strictures of tough legal bulwarks against eviction, a Giuliani-esque wave of economic empowerment has swept the city’s center, spray-brushing away signs of endemic poverty in ironic lockstep with scheduled protests by social-justice movements ranked by those who casually grab a bite after the march. Crowds are swelling along the planned corridors.

Most of Murat Kelle Paça’s clientele stumble in between 1 and 5 o’clock in the morning, after a boisterous night of drinking, concert-going and dancing. Located in the heart of Beyoğlu and surrounded by the best nightlife in Istanbul, if not all of Turkey, Murat attracts one of the most diverse crowds of any restaurant we have seen in Istanbul. During the day, the usual blue- and white-collar crowd – from lawyers to bankers to store attendants – trundles in during their lunch break. But flash-forward to nighttime and the scene becomes much more interesting.

I can’t think of a more comforting dish than soup. It can be as simple or complex as you wish, and as cheap or expensive as you can afford. Just open your fridge or pantry, and you’re sure to find something to turn into a liquid meal – vegetables, herbs, spices, meat, poultry, seafood, grains, legumes… the list goes on. If you’re looking for a restoring bowl of soup in Greece, one of your best bets is a late-night restaurant (many operate round-the-clock) or diner. These spots, some of which are located near or inside central food markets, are perhaps best known for serving patsa (πατσά), tripe soup, a hangover helper as well as fuel for people performing hard labor early in the day – like market workers do.

Caldos de Gallina Luis – which a friend had been raving about to us for months before we finally made it there – is essentially a street food stand that has been trussed up to look more like a sidewalk café. Just a short walk from the Insurgentes metro stop, the venue is located on a side street next to a parking lot and opposite a sex shop, the glowing neon of the shop’s sign casting its pink light over pedestrians walking by.

Caldo verde, Portugal’s most famous soup, doesn’t sound like much in English – “green broth” is the literal translation. I was thinking about this when reading an article on the 20 best soups in the world, which a friend sent to me, noting that caldo verde (a “homey soup” where “thinly sliced greens meld with potatoes and onions”) had made the cut. The article refers, in general, to the restorative power of soup, a belief that is held in very different cultures across the globe – which sounds about right to me. But then the author references a book that broadly defines soup as “just some stuff cooked in water, with the flavored water becoming a crucial part of the dish.” And I have to disagree there, because caldo verde is so much more than flavored water. How to explain that it is a feeling?

Take a rich chicken bone stock and toss in a handful of whole ground spices and herbs. Add a whole chicken leg, braised until the meat is almost sliding off the bone. Slip in a bouquet of cooked vegetables – the bare minimum being carrot, broccoli, bell peppers, eggplant and potato – and serve alongside rice. This is a classic Hokkaido soup curry, a spicy, vibrant soup-and-rice dish guaranteed to warm even the cold, dead bodies of your enemies. But this isn’t its final form. Like the Choose Your Own Adventure books of the 1980s, you can customize almost every aspect of your bowl.

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.

Any Shanghai denizen who has lived in the city for longer than a few months worships at the altar of xiǎolóngbāo (小笼包). These steamed buns of goodness – tiny pork dumplings with a slurp of soup wrapped up in a wonton wrapper – provide delicious fodder for debates among Shanghai’s fiercest foodies.
