“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.

Porto is a postcard-perfect city, its beauty easily captured in a single frame -- monumental churches dressed in deep blue tiles line a steep street opening up onto a view over the Douro River to Vila Nova de Gaia on the other side of the river, where the city’s famed Port wine lodges and their iconic billboards dot the hill. A visit to Porto is often distilled into just such an image, quite pleasantly, but it barely scratches the surface of the city.

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.

At first bite, the flavors don’t seem that different. But then comes a rush of spice or an unfamiliar herbal note, and it’s clear that this isn’t standard Greek fare – in fact, it’s not Greek at all. It may serve a community of Greeks, but – as its name implies – the Association of Greeks from Egypt (SAE) specializes in Egyptian food. What began as a small canteen providing the familiar tastes of home for the association’s members has grown over the years into a popular local hangout, dishing up traditional Egyptian dishes to Athenians of all persuasions. Despite the long and storied history of Hellenistic culture, which stretches into antiquity, the modern state of Greece is relatively young, and like many nation states, its story is bound up in migration.

There’s a saying in Naples: “Anything fried is good, even the soles of shoes.” You may laugh, but we wholeheartedly agree ¬¬– frying may have a bad rap in some parts of the world, but it can add a richness and flavor to any type of food (and, perhaps, even footwear). Think of a dull, bland zucchini or eggplant; when fried right, it becomes a pleasure. We normally get our fried fix by ordering a cuoppo, a paper cone filled with crispy morsels. This symbol of Neapolitan fried street food is our typical mid-morning snack – while going about our morning errands, we munch on the small bites of fried deliciousness that are swaddled in the plain brown paper.

The steam table is an often misunderstood – even maligned – concept. For those unfortunate souls who know only a lackluster corner deli, it's a repository of “food that’s been sitting around all day.” A restaurant inspector might insist on stricter criteria – something to the effect, perhaps, of maintaining already-cooked foods at safe holding temperatures by displaying them in pans above a bath of hot water. For us, particularly in the case of a praiseworthy steam table, it's "a picture menu in three dimensions.” A poetic definition, perhaps, but to us it rings true. Some displays of prepared food, we’ll agree, are not steam tables. They include the multitude of bins filled with ingredients waiting to be wedded in a Sichuan dry pot; the disposable trays, resting on wire racks above (tiny) flames, at a monthly Indonesian bazaar; or the bounty of pork and potatoes at any number of Ecuadorian street carts.
