On this seven-day culinary experience, we’ll be studying the city of Istanbul through its kitchens.

Settling into our first cross-country journey in Turkey many years ago, we were pleasantly surprised by the comforts of Turkish bus travel. The young garson wore a proper uniform and dribbled cologne onto our hands every hour or so. Tea was served regularly, accompanied by one of our early Turkish culinary discoveries, Eti brand pop kek – those unctuous and delicious cakes frosted or stuffed with everything from raisins to chocolate – the Anatolian Twinkie. Call us heathens, but we love them. We’ve tried many traditional Turkish cakes, but none we encountered measured up to the beloved pop kek. That is, until one recent visit to Fatih Sarmacısı, an Ottoman-era shop making our new favorite cake, sarma (the word means “wrapped” or “rolled up” in Turkish).

Istanbul's dessert culture mirrors the richness of its broader culinary diversity and depth, and the city is home to numerous classic establishments that have essentially perfected favorite Turkish sweets. There’s Özkonak’s tavuk göğsü, a dense, thick pudding made with shredded chicken breast and topped with cinnamon, and Mahir Lokantası’s irmik helvası, a subtly sweet mound of semolina paired excellently with a dollop of vanilla ice cream. Despite these and numerous other beloved desserts having firmly established their places on Istanbul's menus, the city also has a penchant for being consumed with the latest trends, often hybrids of local staples or imports from afar. In 2012, we remember lots of folks going berserk over trileçe, a version of Latin America’s tres leches cake, which one can guess from the name is traditionally made with three types of milk.

In these days of viral Instagram videos and WhatsApp chainmail, Turkish ice cream has become synonymous with fez-clad pranksters swooping and slinging a mound of sticky Kahramanmaraş dondurma (ice cream) out of the hands of questionably amused tourists. But Turkey’s dondurma tradition goes far beyond these attention-seeking tricks. Beloved institutions offering more than simple (though delicious) chocolate or pistachio – like Kadıköy’s Dondurmacı Ali Usta, the countless Mado operations, Dondurmacı Yaşar Usta and Bebek’s Mini Dondurma – will never lose their loyal customer base. With such a wealth of frozen creams, it’s no surprise that gelato only arrived on the scene in Turkey in the mid-2000s, when the first Cremeria Milano opened its doors at the Tünel terminus of Istiklal Avenue (it now has some 18 locations throughout the country).

From downtown Athens, one’s eyes rest on the timeless vision of the Acropolis up on the hill, looming grandly above this ancient Greek city. But in the bustling market streets below, another classic, though less well-known, Athens exists.

The historic Plaka district might be one of Athens’ most popular tourist destinations, but there’s another part of the area that visitors rarely see, one where the city’s ancient heart beats a little louder. Under the shadow of the Acropolis, this is the place that saw the birth of classical Greek and Western civilization and also the turbulent arrival of Christianity. There are traces here of the ancient Greeks, Romans, Byzantines and Ottomans, found in the ruins, churches, local houses and – most importantly – in the food

On this tour– our own take on a classic Athens Sunday – we will start off at a leisurely pace, enjoying the quiet streets of normally bustling downtown. At our first stop, a dairy bar that has been around since the 1930s, we’ll get a taste of true Greek yogurt, topped with nuts and honey, as well as of galaktoboureko, a traditional custard-filled dessert sandwiched between syrupy layers of phyllo. Crossing Aiolou Street – one of the oldest paved roads in Athens, dating back to the 3rd century – we’ll walk past buildings and monuments representing the breadth of Athenian history and then catch a glimpse of parishioners at a nearby Greek Orthodox church as they leave the Sunday service. From there we’ll continue to a local spot where we’ll taste loukoumades, small balls of fried dough drizzled in honey that are traditionally enjoyed at weddings, while in a neighborhood spot that serves regional delicacies from across Greece we’ll sample ladenia, parcels of dough filled with feta, capers and chopped tomato, a specialty of the small Aegean island of Kimolos.

Wandering around the neighborhood of Çarşamba, home to a famous weekly market and close to the sprawling Fatih Mosque complex, we get the distinct impression that this area is honey central: the streets are lined with shops selling the sweet nectar, particularly stuff coming from the Black Sea region. “This area is full of honey sellers,” Aslan confirms on a cold November afternoon after we took refuge in his store, Balmerkez, “but there is no place like this.” He’s right – there’s something about his storefront that we found particularly appealing on that cold day. Perhaps it’s because Aslan’s little shop looks more like an atelier than a commercial outlet. Pots, containers, glass jars and wicker baskets are stacked high on the shelves – a honey lab may be a more fitting description.

Located near the end of Akşemsettin Street in Istanbul’s Fatih district is a small yogurt shop that radiates history. Barbaros Yoğurtçusu has been around since Kemal Kurap’s grandfather Abbas came to Istanbul from Albania at the dawn of the 20th century and established the business in 1918. The current location in Fatih was opened in 1946, but the brand’s name comes from its original locale at the Barbaros Hayrettin Paşa ferry pier in the district of Besiktaş, named for the legendary Ottoman naval commander. Like the owners of other classic dairy shops in the city, the Kurap family belongs to a rich tradition of Balkan dairy producers that made their way to Istanbul in the latter years of the Ottoman Empire.

Sold by the slice, pizza is emblematic of New York City. It’s an inexpensive antidote to hunger pangs that can be ordered quickly, and eaten quickly, even on the go. Think of Tony Manero, the John Travolta character in Saturday Night Fever, double-decking a pair of slices while strutting through Bay Ridge, Brooklyn. At a less bouncy pace, we recently visited Astoria, Queens – home to what might be the densest concentration of pizza purveyors in the borough, including some that beckon customers from all across the city – in search of good slices. Some took the form of a triangle, cut from a circular pie; others were squarish, a shape that in recent years has become trendy in Manhattan but that for decades has been a staple in New York’s outer boroughs.

Once the stomping ground of sailors and the Corsican mafia, Marseille’s oldest district, Le Panier, has evolved into a tourist hub and creative neighborhood. Its winding streets are peppered with ateliers (like blade smiths, chocolatiers and painters) and the 17th-century facades are canvases for colorful murals. One of them, a powerful black-and-white image of a couple kissing, faces the funky cantine and concept store, Ahwash. Its owner, Amar, commissioned the Alberto Ruce work – a sign of the artistic energy infused throughout his unique place. Named for the traditional Berber dance in which men and women mix together, Ahwash is a blend of Amar’s worlds – of Morocco and France, of art and cooking. “Eating here is like coming to my house,” he smiles, serving tagines to patrons sitting at vintage tables topped with glowing candles, their dripping wax embodying the restaurant’s romantic and relaxed ambiance.

Chefs have long touted – and scientific research has confirmed – that we “eat with our eyes.” Hence the swishes and swirls of plating. Yet the importance of visual stimulation extends beyond food to include restaurant design, a point that is not lost on the all-day café Monsieur Madame. The eye-catching space is so full of ‘60s and ‘70s knick-knacks that you might mistake it for a vintage shop. Vinyl records are used as placemats on the brightly colored Formica tables. Shelves overflow with old cameras and plastic figurines. From wooden crosses to mounted fish heads, the walls offer a visual feast – so chock-a-block with mementos the vivid print wallpaper is somehow mellowed.

Tomatoes, one of the joys of summer in most locales, thrive in Campania’s hot and sunny climate. Yet good tomatoes can be surprisingly hard to find in summer – the oval, longish, rather crisp varieties that are the region’s claim to fame are mostly used for cooking, and the best ones are canned or exported to richer parts of the world. Somewhat improbably, winter is the best time to eat fresh tomatoes in Naples. As soon as the days get shorter and the nights get colder, small cherry tomatoes with a distinctly pointy end start to appear at every vegetable stall and restaurant throughout the city – this particular version of the fruit is known as pomodorino del piennolo del Vesuvio, or simply piennolo.

The name Aristaeus Ethno Wine Bar suggests many things, some puzzling but the most obvious being that wine is served. One look at the menu, though, and it becomes clear this spot is more restaurant than bar. One food item in particular caught our attention: dambalkhacho. We first heard of dambalkhacho some years back when a friend offered us hard, moldy cheese bits cut from a ball about the size of a healthy orange. It was rich, slightly peppery with a sharp, tart finish; nothing like any cheese we had ever tried.

After the Vietnamese War, many of the refugees bound for France landed in Paris. A minority spread out to other French cities like Toulouse, Lyon and Marseille, the latter being a ville refuge (refuge city) due to its bustling port. The small community in Marseille used to be concentrated near Joliette, before its building boom. But now they’re scattered across the city, taking their cuisine with them. No matter, for we know exactly where to go whenever we’ve got a hankering for Vietnamese: We join the line of people waiting for a bowl of pho outside Nguyen-Hoang.
