Lisboetas are serious about their ginja, a liqueur made from a sour cherry of the same name. The fruit might not be so sweet but is fortunately well suited to being turned into this smooth drink, which is enjoyed both as an aperitif and digestif. Our Culinary Crossroads walk in Lisbon wouldn’t be complete without a tipple of the good stuff.

To her friends, Michelle Boyce, the owner of Shelly’s Café, is “Michelle.” That was the name called out by many customers, when arriving or departing, as we sat and talked in her sunny dining area on a recent afternoon. She is, to be sure, also “Shelly,” a diminutive bestowed on her by her mom in Newry, County Down, one of six counties that form Northern Ireland. Years later and an ocean away from that childhood home – Michelle left Newry for New York as a young adult in 2010 – she told us of her continuing “passion to recreate my mom's home cooking.” In that sense, the name “Shelly’s Café” evokes both mother and daughter.

The day two airliners flew into the World Trade Center, we were in Lagodekhi, an east Georgian village on the border with Azerbaijan. We had been in a total daze trying to comprehend the scope of the tragedy from a village halfway around the world where our hosts were offering solace through the bottle. Zaur, a neighbor, showed up the morning of the twelfth with a Borjomi mineral water bottle of his chacha and made breakfast toasts to the victims of New York, to peace, to bloody revenge and so on. Needless to say, we were well under the influence by lunch time and ended up arm-in-arm at a local stolovaya (canteen) with a platter of frankfurters and bread before Zaur put us in a minibus home.

El Practic doesn’t look like much at first glance. The small restaurant is sparsely decorated and populated by a few naked tables. Its location – in front of two massive buildings under construction in Cornellá de Llobregat, an industry-heavy municipality on the southwestern periphery of the Barcelona metropolitan area – is not where many people would choose to set up a restaurant. But chef Andrés Huarcaya was certain people would come. “I’ve worked in so many places,” he said, “and one day it hit me that if you do good work – this is the key – then people will come. On this street, nobody passes by at night. And yet we are always packed on Fridays and Saturdays – totally packed!”

“Two kilos five liraaa! Two kilos five liraaa!” bellowed a young and exuberant vendor of tomatoes to the ongoing stream of frugal-minded shoppers making their way through the snaking Tarlabaşı Sunday Market. Hundreds of sellers of fresh produce, dairy, seafood, kitchenware, clothing, smuggled tobacco, jewelry, fresh baked goods and numerous other items set up side by side in the central Istanbul quarter of Tarlabaşı every Sunday, weaving an extended path down a backstreet that incorporates both unbridled chaos and strict organization. It is just one of hundreds of similar weekly semt pazarları, the beloved Istanbul neighborhood bazaars that offer some of the cheapest prices on the widest variety of goods the city has to offer, while at the same time serving as a critical element in maintaining the vitality of Istanbul neighborhood life.

Forty years ago, José was the most popular boys’ name in Portugal. It had been the undisputed leader in that category for several decades. But trends change, and in 2017 José didn't even crack the top 20. So, it's quite possible that the future will bring an influx of restaurants named after Santiago, the top choice for the last two years. But as we write this there are still a lot of Zé(s) – the shortened form of José – around town. Zé da Mouraria is famous for its magnificent roasted codfish. Zé Varunca serves great food from Alentejo, the home region of this particular José. And the list goes on: Zé dos Frangos, Zé Carioca, Tasca do Zé and, of course, Zé dos Cornos.

Lahmacun is the perfect savory snack: crispy, oven-fired crust, light and spicy meat spread, a fresh green garnish and a tangy spray from a lemon. We sample some of the best in the city on our Two Markets, Two Continents walk.

There are many legends and myths surrounding the Pyrenees. Some claim that the divine hero Hercules created the mountains by piling up rocks as a tomb for his love Pyrene, who had died in one of the area’s forests after being bitten by a snake. While a romantic story, the Pyrenees are much more than a mausoleum and a symbol of mythic love – they are also the birthplace of Basque culture and a disputed border between Spain and France, a place crisscrossed by Roman roads and sprinkled with Roman architecture, a key point in the Camino de Santiago (Way of Saint James) and a legendary land for the Catalans.

Greek food has been experiencing a renaissance in recent years – an unexpected byproduct of the country’s economic struggles. Greeks are rediscovering their culinary roots, and the world outside is also taking a new look at the country and its cuisine, raising Greece’s profile as a culinary destination in the process. But running parallel to this tale of economic stagnation and culinary resurgence is the story of economic migrants and refugees, people who fled to Europe in the hopes of finding a better life. While the focus as of late has understandably been on the Syrian refugee population living in camps throughout Greece, economic migrants from a wide range of countries have been quietly toiling away in Athens for years.

Over the last couple of years, Rio de Janeiro’s food scene has experienced a Peruvian invasion. Encouraged by the buzz of the 2016 Olympic Games, more than 10 restaurants and bars focused on Peruvian cuisine opened up shop in Rio. But many of those spots are fine dining establishments, plating up the kind of sophisticated cuisine found in Lima – the capital of Peru is a culinary powerhouse and one of the best places to eat in the world. But there are exceptions. We stumbled on one in an old house in the Botafogo neighborhood. At this restaurant, called Pop up Peru, there are no fancy decorations, nor any kind of complex contemporary recipes. Even Lima’s influences are conspicuously absent.

In the Kurtuluş district of Istanbul, we’ve lately been exploring links to older, nearly lost Istanbul culinary traditions. Spending time in the sweetshops, milk bars and şarküteri of this district, we’ve seen a glimmer, if faded, of the “Old Istanbul” that people remember from the 1950s and '60s, when the city’s historic minorities – Greeks, Armenians and Jews – played a prominent role in the culinary scene of the city. It’s a complex and endlessly fascinating subject, one that never fails to spark our curiosity. And then we were distracted by the smell of fresh bread. Fresh lavaş, to be more specific, being hoisted out of a fiery hole in the floor on a blackened hook by the sturdy Gül Hanım.

Once the Christmas nativities are packed away, after the New Year’s cotechino sausage and good luck lentils have been eaten and the Befana witch has filled epiphany stockings with candies, something strange happens in the old center of Naples. It erupts in flames. As the January sun sets, just as the days begin to lengthen, Neapolitan men light small bonfires in the dark alleys and decadent piazzas that lurk beyond Via Foria, the ancient boulevard that slices through the town’s Forcella and Rione Sanità quarters. The fires begin small. Men merrily douse bits of the Gazzetta dello Sport with gasoline, searching specifically for errant wrinkled pictures of Higuaín, loathed former Napoli footballer traded to Juventus.

Scan almost any menu in Lisbon and you’re bound to find bacalhau (salt cod) in some form. That should come as no surprise: Lisboetas have long had a taste for this preserved fish, which can be found in a number of traditional dishes. Yet despite being seemingly everywhere, there are very few spots that focus exclusively on bacalhau. A Casa do Bacalhau, as its name suggests, is one of them, using salt cod in almost everything it serves except dessert. Open since 2000 in the Beato neighborhood, the restaurant is housed inside the old stables of the Duques de Lafões palace, which was built after the 1755 earthquake.

We are on the eighth floor terrace of a relatively new apartment building in the Vedzisi neighborhood, nodding our heads with joker grins like gawkers at a freak show. The view is as spectacular as they come in mountainy Tbilisi, but that’s not what we’re chuckling at. There are 43 ceramic urns – kvevri – buried almost a meter and a half into a bed of sand and perlite in what was supposed to be a swimming pool for a nine-year-old boy. But in an epiphanic moment, the child’s father, 43-year-old doctor, Zura Natroshvili, decided to build a marani in the sky instead. The father of modern advertising, David Ogilvy, once said, “The best ideas come as jokes.” Dr. Natroshvili would probably agree. His friends thought he needed psychiatric help when he first shared his idea.

Cava, the Spanish sparkling wine, is an indispensable part of celebrations in Barcelona – though we’re happy to find other reasons to raise a glass of the stuff any day of the week (particularly on a dreary Monday). It’s produced using the same méthode traditionnelle that is used for French champagne: after the base wine is fermented from the pressing, it’s bottled, usually with a mixture of sugar and yeast, to undergo a second fermentation to produce that ebullient fizz.
