Surrounded by construction sites, Salı Pazarı – literally “Tuesday Market” – is a huge open-air bazaar in Kadıköy, a district on the Asian side. This sprawling market, held on Tuesdays and Fridays, is a snapshot of life in Istanbul: old ladies plow through crowds, their trolleys overflowing with groceries; vendors scream at the top of their lungs; and cars rocket down the highway along the front side of the market. In addition to being a litmus test of Turkey’s economic state and the general mood of the people, the market and the produce showcased on its stands reflect the changes in the seasons. In fact, as spring has been struggling to assert itself this year, only a few stands are stocked with the typical spring products on the sunny but cold April morning that we visit.

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.

It’s 5:20 in the morning and while most lisboetas are still sleeping, Lurdes and Ermelinda Neves are already arriving at the Mercado da Ribeira in the Cais do Sodré neighborhood. Cooks and chefs from Lisbon’s restaurants start showing up at this central market at 6 a.m., and these two seafood sellers need to prep their stall for the day. On this April day, there are clams, both from Setúbal and the prized ones from Ria Formosa, in the Algarve; sea snails; the beloved percebes (gooseneck barnacles); mussels and canilhas (a kind of small and spiky whelk) from Peniche; and cockles and shrimp of different origins – although the best seafood usually comes from the southern shore, the western coastline also yields some excellent specimens.

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.

Nine Inch Nails. Metallica. Tool. Rage Against the Machine. The driving beats, shredding guitar solos and iconic howls are attention grabbing to say the least as you meander through the colorful labyrinth that is Mercado de Coyoacán. From its famous tostadas and comida corridas to spiritual cleansings using Santa Muerte magic and all things Frida (it’s located just three blocks from Kahlo’s Casa Azul, arguably the most visited site in Mexico City), the Coyoacán Market is always abuzz with diners and shoppers, as many locals as tourists. In this case, the music is coming somewhat incongruously from behind an array of fresh-cut flowers: lilies, sunflowers, hydrangea, roses, carnations.

A tomato is a tomato, or that’s what it might seem like to grocery shoppers in Barcelona. But Karim, who currently oversees two hectares of organic gardens in Campíns, an area northeast of Barcelona located at the foot of the Montseny mountain range, knows otherwise. “We don’t know what we eat,” he tells us. “I used to work at other places dedicated to industrial farming, and they added a powder to tomatoes to force them to mature in a couple of days. There was a storeroom where we had to put on a special protection suit before entering [the greenhouses] because the tomatoes were sprayed with harmful products that could go directly to our bones.”

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.

Japan is well known for its variety of national dishes, as well as local specialties claimed by individual regions and cities. Tokyo, which boasts more Michelin stars than any city in the world, is a natural nexus for these disparate eats, as well as more international fare. It may come as a surprise, then, that Tokyo itself only really has one true homegrown specialty: monjayaki. The baseline ingredients for monjayaki, often referred to simply as monja, are nothing more than wheat flour and dashi, that ubiquitous Japanese broth made from kombu (kelp) and shavings of katsuobushi, dried, fermented and smoked skipjack tuna. Cabbage is also common enough to be considered a third basic ingredient.

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.

There is a day in February when we raise our noses to the sky like dogs and catch the first teasing wisps of spring. Our eyes widen, we nod and chime with giddy grins, “It’s coming.” Then the weather turns with a cold snap or even snow and we forget all about spring until one day in mid-March we wake up, pour a coffee, peer out the window and cry out, “Whoa, look!” jabbing our forefingers towards our tkemali tree and its little white flowers that bloomed overnight; the first blossoms of the year. No fruit says springtime greater than tkemali, which is a cherry plum (prunus cerasifera) harvested young, when it is exquisitely sour. Together with fresh tarragon, it is the basis of the mandatory Easter dish, chakapuli. People are stocked with preserved sour plums just in case Easter falls too early on the calendar.

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.
