At 10 a.m., Juan Trenado, head of cheese production at Finca Subaida, and his team had already been toiling for several hours. They moved efficiently through each step of the artisanal process, expertly crafting block after block of the famous Queso de Mahón on the Mediterranean island of Menorca. “By law” – Mahón has a protected designation of origin (D.O.P.) – “the cheese could include a little sheep’s milk, but ours doesn’t,” Trenado told us, as he directed a gushing stream of watery cheese curds from a wide hose into a big, waist-high stainless steel vat. Slowly, the vat filled nearly to the brim, and Trenado, along with Mònica Mercadal, Head of Cheese Maturation, and Ramon Alonso, a new hire, carefully stirred the curds, breaking them into small chickpea-sized pieces.

From the street, Café Lamas looks almost intentionally nondescript. A fluorescent-lit bar with a glass case of snacks and a few metal chairs would make it identical to any other lanchonete (snack bar) across the city, if it weren’t for the shadowy doorway behind the bar’s aisle. Behind that door awaits a blast from the past. Café Lamas is Rio de Janeiro’s oldest restaurant – a respectable 138 years old in a city that is rapidly putting on a new face as it buzzes with Olympic, hotel and condominium construction – and the place radiates a sense of history and tradition. Bow-tied waiters politely bend as guests enter the dining room, which is dimly illuminated by lamps on ornate cast-iron mounts.

No matter how long your stay in Mexico City, you’ll simply never “taste it all.” In the cycle of each day, from tamales, atole and morning licuados to midday comida and evening tacos, this great culinary city is in perpetual motion. Want Yucatecan cuisine? Oaxacan? Restaurants abound where you can experience the cuisines of other regions, but the street food, fondas and market stalls in general reflect the regional cuisine of Estado de México. To properly understand “Mexican food” and its regional diversity, get out of town. Just a little more than two hours from Mexico City’s Centro Historico is a Pueblo Mágico called Tepoztlán. The bus ride there passes through three national parks along the way.

Phkali, in spite of it's meaty appearance, is actually a vegetarian-friendly Georgian specialty of beets, ground walnuts, vinegar, onions, garlic, and herbs. This version is from Armazis Kheoba, a favorite of ours just outside Tbilisi.

“We say if you leave a Cretan pappou [grandfather] alone in the Cretan mountains, six months later you’ll find him fatter,” said dietitian-turned-restaurateur Panayiotis Magganas. He smiled wide. “Our land is incredibly rich.” The fertility of Greece’s largest island is part of the inspiration behind Peskesi, his restaurant in old town Heraklion that showcases the diversity of Crete’s cuisine through recipes he says are slowly being forgotten. “Even people from Crete don’t know some of these dishes,” he said. Set in an intricately refurbished Byzantine-era mansion, the restaurant still retains some of the charming details of the once-collapsing space, including a 100-year-old lemon tree that is the centerpiece of one dining room.

It might have become one of the more fashionable places in Rio for a caipirinha, yet the name of this father-son joint – “Portuguese Kiosk” – suggests humility. Indeed, the pair got their start a decade ago in one of the numerous huts that line the city’s beaches. While the majority of their competitors served the tasty, tried-and-true Rio basics – traditional caipirinhas made with cachaça; beer and French fries – to sandy-toed beachgoers, Manoel Alves, now in his early seventies, wanted to offer something different. He tried importing cheeses from Portugal, his parents’ homeland (hence the venue’s name), but found that the international products went bad too quickly to please health inspectors.

We are sure that many parallel universes exist within the labyrinthine Grand Bazaar of Istanbul, one of the world’s biggest and oldest covered markets. The easiest one to access is a world of Prada knock-offs, Minion keychains and leather-bound menus presented with “Please, monsieur, fresh fish, Turkish kebab, hola!” This is the world constructed for foreign tourists, but step off the main streets and into the bazaar’s tiny arteries, and, as if stepping through a magic wardrobe, you’ll be transported into the local life of the bazaar.

Queens these days is New York’s street cart central. According to the Street Vendor Project, which advocates for vendor rights in the five boroughs, the largest concentration of street vendors with licenses lives in that borough. This concentration of streetside sellers is easy enough to see on six-mile-long Roosevelt Avenue, which runs through six of Queens’ most ethnically diverse neighborhoods with a dizzying assortment of vendors catering to almost every taste and nationality, depending on the time of day. It’s not always easy work. At a recent monthly meeting of street vendors in Corona, Queens, the air was thick with grievances about the conditions they have to work under.

Bodega Manolo has an excellent wine and tapas selection and is one of our favorite spots in Barcelona. The bodega is an essential part of the city's culture, and we have an entire walk devoted to it!

We were cutting grapes in a vineyard in eastern Georgia’s Kakheti region when two young men led a goat by a rope to a nearby tree and sliced its neck with a hefty hunting knife. Our lunch. They offered us a sliver of fresh raw liver with sardonic smiles, insisting it was the best part, but we passed and waited for the meat to be cut, skewered and roasted over the coals of tsalami, or vines. Served with bread, razor-sharp sheep cheese, whole tomatoes, cucumbers and rkatsateli wine, nothing could have been more Kakhetian. Since that harvest, we have been to scores of Kakhetian restaurants in Tbilisi, most of which were gratifying, but none had goat on their menus.

When in season, fried hamsi (anchovies) and tekir (mullet) are among the tasty treats encountered on our Two Markets, Two Continents walk in Istanbul.

Watching old Greek movies from the 1950s, '60s and '70s has been a rite of passage for every single generation raised in Greece from the '80s onwards. When we were young, these movies played endlessly on TV, getting us acquainted with the Greece our parents grew up in.There were a number of things that both puzzled and delighted us – chief among them, the patisserie-as-meeting-place. The heroine, wearing a pillbox hat over expertly coiffed hair, would meet her girlfriends or potential love interest in grand-looking pastry shops, where she would be served by waiters in uniforms and eat a pasta, an individual portion of dessert: soft sponge cake with almond and cream or chocolate fillings.

Cacilhas is the waterfront area of Almada, a small city reachable via a €1.20 ferry ride from Lisbon’s Cais do Sodré terminus. The district is heavily marked by its shipbuilding past and has an industrious character that, for now, is still preserved in its food culture. Right in front of its boat station is a concentration of traditional marisqueiras, typical seafood houses from where you can glimpse a sweeping view of almost the whole of Lisbon across the other side. The seafood platter is a must in any of these traditional spots. It is usually composed of stuffed crab, spiny lobster and giant prawns, accompanied by the classic amêijoas à bulhão pato – clams cooked in garlic, coriander, pepper and olive oil.

Athletes, spectators and everyone else gathered in Rio for the Summer Olympics will have no shortage of good eating options – and not just in the usual touristed areas. We’ve rounded up some of our favorite spots around town. CADEG The 100,000-square-meter market is divided into three warehouse-style floors, with a pavilion just for flower sales at the rear of the second floor. (The building sits on an incline, so you can enter from the street either on the ground floor or from behind the second.) The market is open 24 hours. Early mornings on Thursday and Saturday are the top time for flower shopping. Saturday afternoon is Cantinho das Consertinas’s Festa Portuguesa, with up to 1,000 attendees queuing for a host of salt cod dishes on the second floor.

Mexico City is blessed with great weather all year round. Summer is not very hot because it’s the rainy season, and at 2,200 meters above sea level, things cool down very fast as soon as the rain starts falling. However, we still get our hot days, especially in the spring, and even early afternoons in summertime can make us break out in a sweat. Two of the many delicious ways we have to cool down are paletas (popsicles) and raspados (shaved ice). Paletas and raspados are popular treats all over Mexico, but they’re especially popular among schoolkids. It's common to see paleta and raspado vendors around schools waiting for eager little customers at the end of any school day.
