The resilient almond tree flourishes in a dry climate with very little water, which makes it an ideal tree for Greece, especially in the south and on many of the islands. So it’s no surprise that almonds have featured prominently in Greek cuisine and pastry making dating back to at least the 3rd century BC, or so historians believe. Today in Greece you’ll most likely find almonds in desserts or sweet treats. Since this particular nut generally symbolizes happiness, prosperity and good luck, it plays an important role in Greek weddings and baptisms, with sugared almonds and other sweets made with almonds, like amygdalota, being offered post-ceremony.

It’s a quiet Tuesday lunchtime when we pass through Eleftheroton Square in Chalandri, one of Athens’s northern suburbs. Anyone living in the surrounding areas knows that this boisterous neighborhood is the best place to shop and go out, whether for a bite to eat or a drink. From small, quiet bars to gourmet restaurants, from cafés to wine bars, Chalandri has something for everyone. As expected, the square is dotted with places to sit and enjoy a coffee or have a meal while watching the world go by. Most of them are large, expensive-looking, and completely empty, apart from Ouzeri O Mitsos, a simple, teeny-tiny place squeezed amongst them, which is slowly filling up with customers.

Día de los Muertos (Day of the Dead), or at least some variation of it, has been an annual celebration in Mexico for over 3,000 years. During the Aztec period, it took the form of a festival in August dedicated to Mictecacihuatl, otherwise known as the Lady of the Dead. Today it is one of Mexico’s most colorful holidays, encompassing popular traditions both old and new. To the Aztecs, death was nothing to be feared; it was but a passage and a continuation to the next level of consciousness. Life was viewed as a state of dreaming and death was when someone was truly awakened from their slumber. The Aztecs’ monthlong festival was meant to honor those who had passed on and to entice their souls to visit once more.

Saffron may be most commonly associated with Iran, currently the world’s largest producer of this costliest of spices, but it has a long and storied history across the Mediterranean, particularly in Spain. Once an important saffron producer and trading center, Catalonia has seen a resurgence in saffron cultivation in recent years. The spice, which comes from the Crocus sativus, a fall-flowering crocus, has a long history; ancient civilizations, including the Persians, Egyptians, Greeks, Romans and more, put saffron in all sorts of foods and drinks, and also used it for medicinal purposes and as a dye. The common belief is that saffron was introduced to the Iberian Peninsula by the Moors in the 9th or 10th century.

In the sections of China’s Jiangsu Province where Huaiyang cuisine reigns supreme, autumn is marked not by yellow and red foliage or falling temperatures. The change in seasons instead comes when restaurants post hairy crab (大闸蟹 Dàzháxiè) menus and shops selling baked goods the rest of the year pivot to aquariums full of the live crabs trying to scale the glass walls. Peak hairy crab season falls during the ninth and tenth lunar month of the year. In 2017, that means from October 20 until December 17. But when we arrived at Yangcheng Lake – a hairy crab mecca – before China’s National Holiday on October 1, the lake was already lined with hawkers wrapping the live crabs with twine and selling them to hungry tourists.

Late October marks the start of the olive picking season throughout Greece. From Thrace to Crete, from Corfu to Lesvos, and even in the suburbs of Athens, landowners lucky enough to have olive trees will start harvesting their fruit. And the harvest may continue for another six months. On Crete, for example, where neat rows of low trees cover vast areas, civil servants are given leave to collect their olives in January and February. On Corfu, on the other hand, where the giant trees are too tall for easy harvesting, the common practice is to spread black nets underneath them and wait for the fruit to drop. They collect it once a month until late spring.

I used to joke that the only thing binding together Spain is the classic tortilla española, which in Catalonia we refer to as the tortilla de patatas – a neutral name. This potato omelet is one of the very few traditional dishes that is prepared the same way (and equally beloved) throughout Spain’s Autonomous Communities, the regions created after the Spanish Constitution of 1978, a necessary step towards creating a democratic country after the end of Franco’s dictatorship. The fact that this is one of the few dishes we all have in common highlights the significant regional differences of our traditional cuisine, despite our common Mediterranean culinary culture.

Bar chats are on fire these days in Barcelona. As the controversial Catalan independence referendum draws closer, it’s not uncommon to witness spontaneous private discussions or overhear customers express passionate or indignant comments while reading the newspaper or watching the news on the bar’s TV. There is tension in the air, and bars, perennially popular agoras for debate, have become even livelier places. Many Catalans, whether pro-independence or not, will find themselves voting under difficult conditions on Sunday, October 1, in the controversial referendum organized by the Catalan government.

If Istanbul had a city museum, in the 20th-century exhibition we’d expect to walk into a life-sized recreation of Kenan Usta Ocakbaşı, a seminal grill joint in the Beyoğlu district. As visitors descended a few steps into the exhibition, sensors would trigger the harsh light of fluorescent bulbs overhead, illuminating a room covered in photographs of husky men with mustaches posing with a stout man in an apron, grill master Kenan Usta. The somber, groaning warble of the great Arabesque singer Müslüm Gürses would cue up in the visitors’ rented headsets and ducts inside the replica grill would belch out smoke scented authentically by grilled meat.

Mexicans can mark their calendars by what they’re eating: moles for weddings, pan de muerto for Day of the Dead, lomo and codfish for Christmas and chiles en nogada for Independence Day. Every September 15 and 16 Mexicans gather together to celebrate their independence from Spanish rule. This movement started in the city of Dolores Hidalgo, in the state of Guanajuato, the night of September 15, 1810, when Father Miguel Hidalgo y Costilla gave el grito de Dolores (“the Cry of Dolores”) that ignited the War of Independence. This war lasted until 1821, when Agustín de Iturbide, who later became the first Mexican Emperor, signed the Treaty of Córdoba that granted Mexico its independence.

Traveling out to the Nakameguro district from central Tokyo is similar to a trip from midtown Manhattan to Greenpoint, Brooklyn. It’s not that far and there are many amusing and delicious reasons to go. Nakameguro is similar to parts of Brooklyn in that real estate prices remain reasonable and artists, designers, chefs and entrepreneurs have flocked there to establish high- and low-end shops and restaurants catering to the hip and trendy. It is now one of the more desirable places to live in Tokyo. Smack in the middle of all things fabulously cool is the yakitori shop Kushiwakamaru, catering to neighborhood regulars as well as a rabid expat community since the mid-90s.

It has the makings of a sitcom: two itinerant chefs, one Greek and the other Peruvian, meet in Portugal and decide to open up a restaurant devoted to their home countries’ cooking. Rather than pratfalls, though, we get Pita.gr, a charming restaurant where during the course of one meal we can feast on ceviche, fresh moussaka and tiropita (a Greek pastry made of phyllo dough, feta cheese, honey and sesame seeds), all at the same table. Having the chance to eat delicious food from both countries feels like a privilege in this corner of the Margem Sul (South Bank), half an hour’s drive from central Lisbon.

In summer, there are just a couple of things that lisboetas will queue for: the beach and ice cream. The city is blessed with good places for both, but between the two, we prefer the latter, which in Lisbon tends to be Italian-style gelato, as served in the most long-standing and successful shops in town. Tucked away in a corner of Restauradores, A Veneziana still has the same façade and is run by the same family as when it opened in 1936. The shop is small, with a big esplanada, or terrace, on which customers can sit and enjoy their treats.

After last week’s horrific terror attack, Barcelona’s Las Ramblas are back to life: candles, flowers and messages written on any available surface share the place with a dense river of humanity walking along the boulevard or having a coffee in one of its terraces. Instead of giving in to fear or hate, Barcelonans have made a defiant show of sticking to their summer routine of going out and taking advantage of their city’s abundant outdoor spaces, turning them into places of healing. With this response in mind, we dedicate our guide to outdoor dining in Barcelona to the victims of last week’s attack and to the multitudes of people that, in all their cultural diversity, always were and will be the peaceful essence of Las Ramblas de Barcelona.

We recently spoke with the wine writer Miquel Hudin about his new Vinologue guidebook, Georgia: A Guide to the Cradle of Wine. Hudin was the 2016 recipient of the Geoffrey Roberts Award, an international wine prize, and was named the Best Drink Writer of 2017 by Fortnum & Mason Awards. He has also published a number of guidebooks on other wine regions. Your most extensive previous wine coverage has been about Spain. How come you decided to write a book about Georgia and its wine? Georgia has simply been a point of fascination for years. But it was frustrating to see the same handful of wines pop up time and again so I made the trip over and dived in deep, aided a great deal by winning the Geoffrey Roberts Award.
