Back in our college days, in the mid 2000s in Mexico City, we spent hours talking with our fellow students about the foods we missed the most from home. When we, the “Oaxacan delegation,” brought up piedrazos, everyone in the room laughed. They could not fathom something with such a name – piedrazo literally means to be hit with a hard stone in Spanish – as being edible. We had no idea that our beloved snack, a true classic in Oaxaca, was totally unfamiliar to the rest of our friends. A piedrazo is a piece of very, very hard crunchy bread (hence the name) with pickled carrot, onions and potatoes, dunked in a fruit- and chile-based vinegar and dusted with chile powder and – if you’re feeling fancy – quesillo (fresh Oaxacan cheese).

Outside of Kristal Ocakbaşı, a small grill joint tucked away on a side street in the Pangaltı neighborhood, Obama sat greeting the regulars who streamed in to watch a soccer game while feasting on kebab. “What’s the news, Obama?” asked one man with shoulder-length white hair. “Selam aleykum, Obama,” said another. One woman patted him on the head and baby talked to him, calling him by the affectionate nickname “Obiş.” Though we’d never heard such fond regard for the American president, Obama – the tanker-sized street dog of Eşref Efendi Sokak – took it in stride, yawning lazily. It was just another Monday night among his adoring constituents.

Cabana do Pescador (the fisherman’s hut) got its start some 50 years ago with a very simple premise: A fisherman named Luís Maria Lourenço decided to sell his leftover daily catch by grilling it on iron barrels halved lengthwise – an old-school upcycled getup that can still be seen at many popular tascas. Since then, this no-frills fish shack has become such an institution that the strip of Costa da Caparica coastline where it sits has come to be known as cabana de pescador as well. Costa da Caparica was originally comprised of small fishing villages. In the 1970s, it became the favorite seaside getaway for Lisboetas, owing to its proximity to the Portuguese capital and its numerous spacious beaches.

In the West, tofu is considered a boring dish desperately in need of other ingredients to make it interesting. Not so in Japan and especially in Kyoto. Tofu is a well-known component of Kyoto regional cooking, and locals consider tofu to be the star of the show. When visiting Kyoto during November and December’s peak leaf-viewing season we always make sure to book a meal at one of the city’s wonderful selection of tofu-centric eateries. Our very favorite is Tousuiro, a Kyoto institution where the tofu is made in house from domestically grown soybeans. At Tousuiro, tofu turns into a dazzling spectacle. The meal is not only delicious: It is the perfect Kyoto experience.

Order a grenadine in France, and you’ll get a glass of bright red syrup made from pomegranate to sip with water for a refreshing quaff. In Armenia, the grenade – pomegranate – is a national icon, depicted in art, consumed at meals and made into a local liqueur. Stemming from the country’s ancient mythology, the grenade symbolizes fertility and abundance, making it a fitting name for Couleur Grenade, a female-owned Armenian restaurant in Marseille. From stuffed eggplant to tchi kefté (beef tartare), Couleur Grenade offers a lexicon in Armenian cuisine. Growing up in Lyon, the restaurant’s owner, Gayane Doniguian was French at school – her friends called her Delphine – and Armenian at home. Cooking with her grandmother at an early age sealed her love for Armenian cuisine.

My memories of helados (ice cream) as a kid in the small Galician town of Vigo in the 80s are mostly of the signs outside kiosks advertising Colajets (a cola and lemon flavored popsicle) and Frigo Pies (strawberry ice cream shaped like a foot) – colorful, industrial fantasies on a stick. The quality ice creams of my town were represented by two unique parlors (Di San Remo and Capri), which always had long lines in the summer. However, these places were reserved for very special Sundays. Barcelona’s version of such traditional spots were the Valencian turronerías and horchaterías (orxaterias in Catalan), where locals could get tasty helados with a more artisanal bent. But as the city grows, many of these longstanding places have been disappearing, leaving Barcelona something of a dry desert when it comes to small-batch ice cream.

Legend has it that huangjiu, or yellow wine, was invented by Du Kang, the god of Chinese alcohol. Annual production starts in eastern China’s Shaoxing region in the tenth lunar month – the temperature and humidity at that time of year create the best environment for making the wine – with sacrifices to Du Kang. The wine is made from fermenting glutinous rice with wheat or rice qu, a cake of mashed grains that cultivate yeast; both convert the starch to sugar then to alcohol. The product of all that fermentation is a sherry-like amber liquid that is used in Chinese cooking or served as a drink paired with Chinese foods.

In business since 1887, Diporto – a defiantly traditional spot in downtown Athens – has no sign and no menu. The staff doesn’t speak a word of English, and you might have to share a table with eccentric old men who look like they stepped out of a folk ballad. You will probably have to mime your order or draw it on the paper tablecloth. But if you ever wondered what it would be like to eat in a working-class Greek taverna circa 1950, read on. Diporto is located smack in the middle of what is – at least by day – one of the Athens’ most fascinating areas, home to a variety of specialized marketplaces. Varvakeios, one of the few of its kind in Europe, is the city’s largest fish and meat market, in operation since 1886. Around this enormous, chaotic market, where vendors try to outdo each other in shouting, lies Athens’ traditional center of trade, with streets devoted to specific merchandise: hardware stores and bric-a-brac on Athinas Street; spices, cheeses, kitchen equipment and plants on Evripidou and Sofokleous; doorknobs on Vissis (yes, there is a street dedicated solely to doorknobs).

Before we cross the Bosphorus Strait to Asia, this story starts on Istanbul’s European side, at a small stand that has been operating in Beyoğlu since the mid-1970s. There, Muammer usta serves up expertly-cooked and sliced cuts of kelle söğüş (chilled lamb's head meat), perched in a strategic location across from the local fish market and a stone's throw from the Nevizade strip of meyhanes and bars. Over the decades, Muammer usta has become one of the most recognizable characters in the area. The usta’s influence cannot be overstated. His stand is beloved by locals, foreign tourists from across the globe and food critics alike.

“When you like what you do, and you're young, nothing is impossible,” says Doña Juanita Hernandez, one of a handful of female master distillers in Oaxaca, the heart of Mexico’s small-scale mezcal industry. She sits, tiny and relaxed on a wooden bench as we sip mezcal in her distillery, El Rey Zapoteco, in the Oaxacan town of Santiago Matatlan. Doña Juanita herself was just a young girl when she started filling and labeling the bottles at her uncle’s distillery. He was the first person to bottle in the town, which has a long-held tradition of mezcal production. “[His brand was] Mezcal Matatlan,” she remembers. “He bought a bottling machine – a tiny one for four bottles at a time, and he had me fill the bottles and put on the labels.”

We were crawling through traffic on Porto’s ring road in our rental car when dawn finally caught up to us, illuminating the spectacular view of the Douro River down below. That slice of the waterfront quickly glided past as we exited the bridge, soon replaced by the lush rolling countryside south of the city: olive trees, low grape arbors. We were on our way to Santa Maria de Lamas to visit the headquarters of the world’s largest cork producer, Amorim Cork. Like most visitors to Porto, one of the first things we did upon arrival was a port wine tasting, perhaps the most famous feature of the city’s culinary culture. It was December 2016, and we had barely unpacked our bags before strolling down to the Douro River’s quays and finding a small spot to partake in this delightful ritual, one that has evolved over centuries.

In the 1960s, Mayor Gaston Defferre proposed a plan to give Marseille a beach that was worthy of the Mediterranean port. Despite the city’s 26 miles of coastline, there were very few public beaches at the time. One of them, Prado, was so narrow that waves would flood the coastal road beside it each time the mistral wind blew. In 1977, the Parc Balnéaire du Prado opened on an artificial embankment, cleverly built with leftover fill from the construction of the Marseille metro. With its gravel beaches and grassy lawns, the sprawling, 64-acre seaside park was an instant hit. Now, the beaches – known as Prado Sud and Prado Nord – are two of the most popular for Marseillais and tourists alike.

At first glance, Berbena, a restaurant in Gràcia, resembles a small, pretty tree with dazzling foliage – it offers a sophisticated and complex dining experience. But the restaurant’s delicate attributes, those pretty leaves, wouldn’t be possible without a carefully tended trunk and roots. In short, the basics matter, something that its creator, chef Carles Pérez de Rozas, decided after years spent in high-end kitchens. Carles had a culinary education par excellence: After studying at the prestigious Hofmann School, a culinary institution in Barcelona, he worked at several Michelin-starred restaurants in Catalonia, such as Drolma, Saüc, and Carmen Ruscalleda’s iconic Sant Pau. A job in the restaurant at the Hotel de Ville de Crissier brought him to Switzerland; he then spent a short and intense period in France with the great chef Michel Bras. In Japan, he trained alongside Seiji Yamamoto, in his Tokyo restaurant Nihonryori RyuGin, adding more notches of refined knowledge to his belt.

New York City has many Chinatowns; how many is a matter for dispute. While the oldest and most famous is in Manhattan, southern Brooklyn now boasts two such neighborhoods – or maybe three, depending on who's counting. Without a doubt, however, the city's largest and fastest-changing Chinatown surrounds the eastern terminus of the 7 train in Flushing, Queens. One measure of Flushing's vibrancy is the variety of spoken languages. Flushing is home to speakers of Mandarin, Shanghainese, Fujianese, Cantonese, Taiwanese and many other Chinese languages and dialects. The neighborhoods immediately to the east are densely populated with Korean speakers; in much smaller numbers, we also find speakers of other East, South and Southeast Asian languages.

When Andres Contreras brings wild hongos (mushrooms) down from the forest, everyone starts preparing for a feast. “I learned everything from my dad. The categories of mushrooms, which were edible, everything,” says Andres on the day we trekked through those same woods he walked as a child, discovering the secrets of hunting for fungi. He makes quick work of the kilometers to the top of the section we are walking, with a hawk-like accuracy for spotting mushrooms and a soft gait despite his chunky rain boots. The area, about an hour outside of Mexico City in Mexico State, has been home to mushroom hunters for over a hundred years and is a parcel jointly owned by several communities in a cooperative structure known as an ejido.
