On our Made in Catalonia walk, we partake in Barcelona’s beloved vermut tradition, symbolized by colorful, 1960s-era carbonated water siphons. Since the end of the 19th century in Barcelona, this ritual – a fresh drink accompanied by tapas composed usually of preserved food, cold cuts, cured or marinated fish or seafood – has been a way to bring people together before meals.

The balık ekmek (fish sandwich or, more literally, fish and bread) – an Istanbul street food staple – has lived and died and been born again along any walkable stretch of the Bosphorus. Whether you’re in the habit of buying it from the neon-lit boats docked at Eminönü’s pier (which, to the chagrin of some and the delight of others, had their leases revoked by the municipality on November 1) or from a street cart illuminated by a jaundiced bare bulb, one thing’s for certain: there’s a better option out there. That would be the balık dürüm (fish wrap) – the fish sandwich’s tastier, spicier and genuinely sexier cousin. In an ever-developing city where centuries-old institutions are taking their final breaths, there is much change to lament. But the introduction of the balık dürüm is one change we welcome with open arms and mouths.

Walk in through an anonymous iron gate, halfway down a road you would assume to be completely spoiled by mass tourism, and a surprise awaits. Casa do Alentejo in downtown Lisbon is one of the many old-school regional associations in the city – but none of the others look quite like this. Many who come across this 17th-century building think they are visiting a Moorish palace, perhaps a remainder of the time Muslims ruled over Al-Ishbuna. It’s a misleading impression. In fact, this was a generic building that served different uses over its long history, including as a residence and as a school.

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.

“Caliente!” Juan calls out, and we all duck to avoid the steaming hot pan as it floats across the kitchen. He holds one side with a folded up towel, the other with a pair of pliers. Kitchen might be a bit of a misnomer. The small stall sits on the sidewalk, with a temporary tin roof overhead and brand new white tarps tied tightly to the back to protect against Mexico City’s afternoon thunderstorms. Each day for the three weeks leading up to Día de los Muertos, the Day of the Dead holiday, Tito Garcia, the stand’s owner, and the rest of the crew, will make hundreds of pan de muerto sweet rolls, as part of the Jamaica Market’s holiday romería.

Pies go back a long way in Athens. Harry’s Kitchen, a tiny pie shop on Axarlian, a small pedestrian street near Syntagma Square, does not – this hole in the wall only opened around a year ago. Yet the pies that Harris Satiridis, the shop’s namesake, and his wife, Yiouli, put out have already gained a reputation as some of the best in Athens. You could easily miss Harry’s Kitchen, it’s that small, but you won’t miss the queue of people outside, waiting to get their hands on one of the very tasty-looking pies in the small display case. And after biting into one, you’ll better appreciate why pies have been enjoyed in Athens since antiquity.

On Sunday around lunchtime, the streets of Sanita can get almost eerily quiet. Where normally children play, scooters zoom past, shopkeepers haggle loudly with old ladies, and neighbors stick their heads out of their windows and discuss the latest gossip, suddenly nobody is to be seen or even heard. Sanita is still a very traditional working-class neighborhood in the heart of Naples, and tradition has it that on Sunday afternoon everybody feasts: The whole family gathers around mama’s table for an hours-long lunch. If you happen to wander Sanita’s deserted streets at that time of the week, you’ll constantly catch whiffs of familiar smells: frying garlic, roasting onions, and meat simmered in sauce for many hours. And, more and more often, the tempting, spice-scented smell of curry.

On our Culinary Secrets of Downtown Athens tour, we tuck into a large portion of yogurt served the traditional Greek way, on a plate with honey and walnuts. Few words do justice to the taste of the yogurt, which is so thick that at points it is almost solid, and the honey and walnuts are the perfect accompaniment.

Anise-based liqueurs are as ubiquitous as outdoor terraces across the Mediterranean. Long prized for its medicinal benefits, anise is the ideal antidote to the region’s sweltering temps, especially when sipped in tall glasses with refreshingly chilled water, as is common practice. From Turkey’s rakı to Italy’s heavily sweetened sambuca, each country has its own recipe. France has two, anisette and pastis, with the latter having licorice root thrown into the mix. Born in Marseille, pastis is the republic’s most popular aperitif, but both beverages are poured at bars around town, whose shelves are stocked with bottles from a variety of producers. There’s one brand, though, that deserves special attention: Cristal Limiñana, one of the city’s last distilleries.

On sunny afternoons in the sleepy neighborhood of Narvarte, crowds of adults huddle around the glass counter at La Gaspacheria, eyes aglow as they consider possible toppings. While the scene evokes children at an ice cream parlor, the ingredients before them strike the uninitiated as a strange mix. Jicama. Hot sauce. Onion. Cheese. Orange juice. Even among chilangos, who famously love to cram their favorite ingredients together in ever stranger combinations (tortas de chilaquiles and tortas de tamales, for example), the idea of mixing orange juice, mango and raw onion gives pause.

The first thing we noticed when we ducked into Koali on a late summer afternoon was the sudden change in ambiance, a veritable culture shock from the sloping, hookah bar-lined street we had just walked down. Keroncong and pop sunda classics, the kind of music you might expect to hear in a beach hut in Bali, drifted softly from the speakers. Each table bore the name of a major Indonesian city, and the walls, otherwise sparsely decorated, were covered with scrawled sayings in Bahasa Indonesian. The sound of liquid hitting a flaming hot wok and the enticing smell of coconut and lemongrass confirmed our suspicions – we had stepped into another world.

In the 1980s and 1990s Bairro Alto was the epicenter of Lisbon nightlife: Bars here had the best DJs, and interesting restaurants were opening more often in this neighborhood than in any other in town. Although Bairro Alto lost some of its more compelling spots over the years, it’s still a party district and on a recent upswing, with promising new restaurants cropping up. Among these is Zé Varunca, a notable ambassador for the food of Alentejo, one of Portugal’s best regional cuisines. Having limited resources, Alentejo cooks learned how to go far with a little, deliciously using, for example, stale bread as a staple ingredient along with chouriço or other sausages, pork fat and sometimes a bit of meat.

Opening a pizza joint in a city that’s world renowned for its pies requires some gumption. Maria Rosaria Artigiano, 56, the energetic owner of Pizzeria ‘Ntretella, which opened a few years ago, certainly has it; so does her brother, the brilliant chef Gennaro Artigiano. The beautiful restaurant they built together has quickly become a “new classic” in the panorama of Neapolitan pizzerias. Gennaro, 57, owns Locanda Ntretella, an old restaurant in the Spanish Quarter known for its excellent cuisine. Yet he is a restless man, always on the lookout for a new challenge. So in 2013, when he heard of an old carpentry shop in the heart of the Spanish Quarter, he visited the space and realized it would be a perfect place to open a pizzeria.

Ramen joints are often easily recognizable, either by large windows illuminating slurping customers, a vending machine dispensing meal tickets at the doorway, or the brightly lit signs; usually it’s some combination of the three. When it comes to Ura Sablon, however, one might easily pass it by. The narrow entrance is tucked away between a storage locker and an air conditioning unit; a small notice, illegible unless up close, is attached to a traffic cone; and the paper lantern reading “tsukemen” – a kind of dipping noodles – could easily have ended up there by chance.

Tortas are modest in appearance – they resemble flattish cupcakes with minimal adornment – but they taste like breakfast at grandma’s to many homesick Filipinas. And tortas are a common bond between Nora Galleros, Jeanette Uy and Khaterine Gadingan – Khaty, to her friends. Nora, Jeanette and Khaty grew up in the Southern Philippines, on the island of Mindanao, and think back fondly to the food of their home city, Gingoog (Hee-ngo-og).
