The arrival of fall always finds us heading instinctively, like salmon swimming towards their ancestral headwaters, to the Balık Pazarı, Beyoğlu’s historic fish market. Autumn is quince season in Turkey and that means the appearance – for a limited time only – of one of our favorite desserts, ayva tatlısı (literally meaning “quince dessert,” although “quince in syrup” might be more accurate). Nestled in the fish market is Sakarya Tatlıcısı, a pastry and sweets shop with old-world charm that is one of our top stops for this dessert. The apple-like quince is one of those complicated, mysterious fruits that take on a new life when cooked. Raw, quinces are often astringent and inedible.

Breakfast in China traditionally consists of something brothy and stomach-filling, such as congee (a rice-based porridge), wonton soup or xiǎolóngbāo (soup dumplings). Also popular are savory fried foods like scallion oil pancakes – in Shanghai, lines of hungry customers waiting to get their morning pancake fix from places like A Da Cong You Bing can literally stretch around the block. It’s thus no surprise that Western-style grab-and-go breakfast options are of little appeal to locals.

The large banner in La Nena chocolatería proclaiming “No Hay Alcohol” (strung up between a rocking horse and a wooden toy kitchen) makes it fairly clear that this is not a place for sophisticated conversation and cocktails. That doesn’t mean that La Nena (which means “The Girl” in Catalan) doesn’t cater to any other vices. Indeed, its delicious homemade cakes, pastries, hot chocolates and savory snacks tempt the residents of Barcelona’s Gràcia neighborhood on a daily basis.

The rubbery, white Cypriot cheese known as halloumi in Greek and hellim in Turkish is without a doubt the island’s most famous culinary delicacy. Served grilled or fried, it has long been popular at tables in Athens, Istanbul and around the region. As demand from Western Europe and even North America has increased in the last decade, exports have shot up. But a new law regulating what goes into the cheese threatens to throw the industry into turmoil.

Like Clark Kent hiding his Superman tights beneath a brown suit and glasses, Klemuri maintains the appearance of a predictable Beyoğlu café – wooden tables, shelves loaded with knickknacks, Buena Vista Social Club on the stereo, spinach crepes and a crispy chicken salad on the menu. But down in the kitchen, out of public view, Klemuri’s alter ego – a spry Laz cook – is waiting to save you from another boring “café” lunch.

There’s nothing like a debate about “urban renewal” – often touted by municipal governments as a way to repurpose run-down urban areas for gentrification – to work up a good appetite. In a city like Istanbul, a teeming metropolis of 15 million people working to build a modern life among ancient ruins, these discussions seem to occur on every corn

There is often some confusion when it comes to the many varieties of dumplings in Shanghai. The city’s most famous snack, xiǎolóngbāo, is a soup dumpling that neatly encases its broth inside a thin dumpling skin. It is not, as many first-time visitors assume, a dumpling floating in soup. For that, we turn to the humble wonton soup.

Diners in Istanbul are spoiled with options for fresh seafood. But most venues are mere caricatures of places like İsmet Baba, where traditions have been kept sacred for more than 50 years. While many other such restaurants are kitschy, İsmet is gritty and authentic. Located in Kuzguncuk, a charming neighborhood on the Asian side of the Bosphorus, it may not be the best restaurant in the city, but it’s got something most of the others have lost: old-school Istanbul charm and character.

Turkey’s take on the pizza comes in two distinct varieties. There’s the Arabesque lahmacun, a round, ultra thin-crusted snack topped with a shmear of finely ground meat and seasoning. Then there’s pide, a more substantial canoe-shaped creation that’s a specialty of Turkey’s Black Sea region.

Don’t be fooled by the name: Derlikatesen does not stand for dirty and delicatessen, as online urban dictionaries would like you to think, but is a combination of “delicatessen” and the Greek slang verb ντερλικωνω (derlikono), meaning eating until one is ready to burst.

With a menu from the frigid provinces that border Korea, Dongbei Siji Jiaozi Wang – literally, “The Four Season Dumpling King from the Northeast” – is all about hearty dishes to warm you up from the inside out. The further north you head from the Yangtze River, the more the temperate climate demands that wheat trumps rice as the staple grain, often showing up on menus as dumplings and noodles. Yet despite its eponymous claim to represent China’s Northeast, not even the Dumpling King can escape Shanghai’s astringent influence, specifically in the condiment selection. Here you dunk your boiled dumplings in vinegar and sweet chili pepper rather than the typical Northern garnish that adds soy sauce to the mix (or sometimes boldly goes it alone with no vinegar), occasionally coupled with roughly chopped garlic.

The sap of the spiky maguey plant has long been used by the indigenous peoples of Mexico to prepare pulque, a milk-colored, viscous drink that has roughly the same alcohol content as beer. When they arrived in Mexico, the Spanish were introduced to pulque. Used to imbibing harder stuff, however, the conquistadors experimented with distilling a mash made out of the maguey plant, in the process inventing the beguiling spirit known as mezcal. Previously a liquor considered the province of the poor and working classes, mezcal has in recent years become one of the trendiest and most popular alcoholic drinks in Mexico, with more than 150 different brands now on the market. (Tequila, made from blue agave – a kind of maguey – and produced within a specific region of Mexico, is the best-known member of the mezcal family.) The rise in mezcal’s popularity has led to a proliferation of mezcalerías, wine bar-like spots that specialize in pouring the drink. In Mexico City in particular, mezcalerías have popped up in nearly every neighborhood, and their numbers keep growing.

Editor's note: This week, Mexico City joins Culinary Backstreets as our fifth city. We're delighted to launch Culinary Backstreets: Mexico City and look forward to sharing our culinary discoveries in this captivating metropolis. The vast megalopolis of Mexico City is one of the most misunderstood and misrepresented cities in the world. Adventurous tourists are often surprised to discover a vibrant national capital filled with incredible architecture, beautiful weather and amazing food. In some ways, this scene has been playing out for 500 years.

Perhaps it’s the proximity of the waters of the Golden Horn or the weathered wood interior, but we get a distinctly maritime feeling at Köfteci Arnavut, a tiny köfte joint in the historic Balat neighborhood. The members of the İştay family, who opened the place in 1947, seem to think the same thing, running the place with ship-shape efficiency.

Is there anything that warms the heart of a food-obsessed traveler more than civic pride in a local culinary specialty? In a country that more often celebrates a particularly polarizing political leader, the great affection among the people of Lanzhou for their famous noodles – which the city has reportedly even sought to trademark – gets our stomachs rumbling.
