Christos Mplantis, a 37-year-old farmer based in Marathon, a region in northeastern Attica, has farming in his blood. His father, Alexandros, was a farmer too, and starting at the age of ten, Christos began joining his father at farmer’s markets, or laiki (λαϊκή), around Athens any time he was off school, particularly during the summers. Although working the land and selling at markets became second nature to him, Christos didn’t immediately think to follow in his father’s steps. He went to technical school to become certified as a plumber but couldn’t find a decent job after graduating. So, around 17 years ago, he found himself in a familiar spot: working next to his father.

Pizzeria Gino Sorbillo has been serving pizza made with bio flour, which is made from grains that haven’t been exposed to fertilizers or other pesticides, and mother yeast, the proportions of which are top secret, since 1935.

On our Keramikos Calling walk in Athens, we visit the weekly open-air market, tasting whatever is in season from the vendors and getting a feel for the neighborhood. 

“I missed the traditional foods I grew up with in Cádiz,” said Natalia García, a young woman with dark hair, bright red lipstick and a smattering of tattoos across her upper arm. “I was actually born in Germany, and my mother was a professional cook, so I was always around food,” she tells us. Despite the German heritage, García’s strong accent and open, friendly demeanor are pure Andalusia. “Whenever I told people [in Barcelona] I was from Cádiz, they would get excited. Everyone loves Cádiz, especially the food.” After living in Barcelona for just one year, García decided to open La Chana, a bar that reminded her of home, in the heart of the non-touristy neighborhood of Poble Sec.

Ask anyone what they know about Georgian food and they’re sure to mention khachapuri, a baked barge of dough packing a cargo of gooey cheese. While khachapuri in its many forms is perhaps the best known Georgian dish abroad, we sample the equally delicious if less flashy tonis lobiani, a traditional bean-stuffed bread, on our market walk.

Traditionally the Portuguese consume large amounts of sugar and cakes all year long, with the most famous being the pastel de nata, Lisbon’s iconic and delicious custard tart – no visit to the city would be complete without trying one. Luckily for you, it’s one of many sweets that we sample on our Culinary Crossroads walk.

Sold for one or two euros, the spritz, which at its most basic is a combination of bittersweet liqueur, sparkling wine and seltzer, has been dubbed “the champagne of the poor” – no wonder it has been the king of cocktails in Naples for at least a decade. Aperitif time – often starring a cool spritz – is the most relaxing, and thus most awaited, moment of the day. And Neapolitans have made an art of this pre-meal ritual. In a city that is known (although sometimes unjustly) throughout Italy as the city of the idle, the aperitif has come to symbolize living well, in the company of friends.

Pa de Sant Jordi, bread striped with the bright yellow and red of the Catalan flag to celebrate La Diada de Sant Jordi, may be the new-kid-on-the-block of culinary traditions in Barcelona, but it’s been accepted by nearly everyone as a genuine part of the holiday. The patriotically colored bread is now a ubiquitous presence in bakeries throughout the city come April 23.

Down the street from Istanbul’s upmarket Etiler neighborhood and above the even-glitzier shoreside quarter of Bebek lies Hisarüstü, a ragtag maze of unplanned urban growth that happens to be adjacent to the newer campus of Bogaziçi University, Turkey’s most prestigious college. Once upon a time the area was home to a pig farm, but Hisarüstü became quickly built up as Anatolian migrants rapidly settled in Istanbul, not shying away from the area despite its location on an impossibly steep hill. Though Etiler and Bebek are among the city’s most prestigious areas, Hisarüstü doesn’t get much attention from outside visitors – if you don’t live in the neighborhood or attend Boğaziçi, you likely have no reason to go there.

While meandering through a market on Istanbul’s Asian side, we spot strings of dried eggplant and peppers that will at some point in the future become extremely flavorful dolmas once they have been rehydrated and stuffed with a rice and herb mixture.

Retsina has a bad rap. Many locals and foreigners associate this Greek classic with cheap “house wine” served at tavernas – you know, the stuff that is bright yellow in color, has an intensely resinous flavor and practically guarantees a headache the next morning. But we think retsina is just misunderstood. Increased demand in the 1960s for this resin-infused wine led to a plunge in quality, sullying its good name. Yet a new generation of Greek winemakers and sommeliers has worked tirelessly over the last decade and a half to restore retsina’s standing in the international world of wine, experimenting with different grape varietals and methods of fermentation in the process.

Like the Proustian madeleine, sweets can stir up all kinds of feelings in the minds of those who eat them. In Naples, struffoli (small, round doughnuts glazed with honey) and cassata (sponge cake with ricotta and candied fruit) speak of Christmas, while chiacchiere (sugar-dusted fritters) and sanguinaccio (literally “blood pudding,” but actually made of chocolate) bring to mind Carnevale. And then there’s pastiera, whose very scent and taste make us think of Easter and spring. These days, pastiera can be made all year long, not only when the wheat has just sprouted, as was the case for our ancestors. Yet, when Easter approaches, all Neapolitans dream of this tart.

The handywork of Pasquale De Stefano, better known as Pasquale ‘o nummararo, “the number man,” can be seen all over Naples. His signs, which he hand paints on wooden boards with ancient paintbrushes, are used by food businesses and fruit and vegetable vendors across the city. On our Naples walk, we visit his workshop to chat with the master himself.

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.

On our Downtown Athens walk, we sample a few of Greece’s many native olive varieties at the city’s central market. The olive tree thrives in Greece, where the land is mostly rocky and steep and the climate hot and arid, and for millennia, olive oil has been as essential to Greek cooking as the gnarled, silver-leaved trees have been to the country’s landscape.
