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.

Mid-Autumn Festival (中秋节, zhōngqiūjié) lands on the 15th day of the eighth lunar month, relatively near the autumnal equinox; in 2017, it falls on October 4 and coincides with the National Day holiday. Also sometimes called Mooncake Festival, it’s a public holiday in China and Taiwan on which families gather to give offerings to the full moon, float sky lanterns and eat mooncakes (月饼, yuèbing). A culinary tradition with legendary roots, mooncakes are sold everywhere from grocery stores to five-star hotels and come with competing origin stories that relate how these sweets came to represent the holiday.

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.

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.

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 Mexican cuisine, sweets are for the most part simple treats that are enjoyed at the park, market or beach, such as caramelized fruits and vegetables, blocks of nuts or amaranth seeds held together with honey, or small rice paper cakes filled with honey. The common denominator of most of these sweets is their simplicity. When it comes to ice cream and other frozen delights, however, the country truly shines, with an astounding variety of cold treats to please sweet tooths of every persuasion. The range of frozen desserts found in Mexico City includes everything from raspados – ice shavings served in plastic bags or cups to which a flavor of choice is added – to Italian gelato served in some of the most sophisticated restaurants in town.

There’s something special about Crete, Greece’s biggest island. The country’s most fertile region, it has a long history of food and wine production that stretches back to the Bronze Age, making Crete one of the most interesting culinary destinations in Europe. Bordered by the Aegean Sea to the north and the Libyan Sea to the south, the island is home to over 70 different edible herbs and wild greens, and local farmers produce a wide range of products, from Mediterranean staples like olives, tomatoes and eggplants to more tropical produce, such as mangoes and papayas.

Every summer, sellers hawking bolas de Berlim – custard-filled doughnuts without a hole in the middle – throng to Portuguese beaches. Plodding across the boiling sand and ringing a bell to announce their arrival, they deliver these beautifully simple pastries to hungry beachgoers, many of whom associate a trip to the coast with the sweet treat. A slew of bolas are sold on the beach each year; the presumed number is almost as eyebrow-raising as the calorie content of a big fat bola filled with custard. It’s no surprise, then, that an app promising to be the Uber of bolas has been an immediate success.

One of the tenets of the Slow Food movement is that it’s impossible to make a really good meal out of industrial food. Of course certain ingredients can pass muster with diners even if they’re grown on an industrial farm. Yet sustainable farming has an obvious impact – it’s not just a matter of better tasting and healthier food but also environmental and societal benefits. In Barcelona, we are surrounded by a large number of independent, sustainable producers that, too often, are completely invisible. They work in nearby provincial areas such as El Prat, El Penedès, El Vallès, El Garraf and El Maresme that give forth a veritable cornucopia of food goods: vegetables, fruits, nuts, legumes, olive oil, cheese, marmalades, cereals, flours, honey, meat, fish, wine, vermut, beer and more. These producers work hard every day to remain independent and adhere to stringent standards of sustainability and quality.

In September of last year, Shanghai eaters were shocked when Mr. Wu shuttered A Da Cong You Bing, the city’s best scallion pancake shop. The only explanation for the abrupt closure was a worn sign on the door that read: “My family has a problem. The stall will be closed for a few days.” But this wasn’t the whole truth. Some attributed the shutdown to the fact that the stall was featured on the BBC program Rick Stein’s Taste of Shanghai, claiming that it had drawn too much attention to the unlicensed vendor and the government had taken note.

The Slow Food movement may be all about slow living, but its spread around the world has been nothing short of speedy. What began as a protest against the opening of a McDonald’s in the Piazza di Spagna in Rome in 1986 has morphed into an international organization that safeguards some of the most authentic and unique local food products in 160 countries across the world, and even receives UN recognition and support for this important work. In Spain, the Slow Food movement mainly consists of independent regional groups made up of chefs, producers and other food-related professionals, and its influence continues to grow as new initiatives are gradually launched.

Quick Bite: On this half-day introduction to Corona’s culinary essentials, we hit the streets on a Saturday, when the griddles and grills in this already lively neighborhood are working overtime and the street vendors come out in full force. To many, the Corona neighborhood of Queens is something of a mystery, a place you only pass over on the elevated tracks of the 7 train as it hurtles towards a Mets game or the restaurants and food courts of Flushing.

The streets are nearly empty. As light cascades down cobbled thoroughfares, dog walkers shield their eyes and market-goers tow their rickety carts toward Mercado de la Bretxa. The market of San Sebastián sits underneath a square just a pebble’s skip from crashing waves surging up the mouth of the Urumea Itsasadarra River. Lamps glowing red illuminate butchers navigating dangling strings of txistorra, Basque chorizo, while across the aisle, an bright white storefront advertises every imaginable form of bacalao, or salt cod. Tucked in a rear corner, Bar Azkena has been crafting delicate fluffy breakfasts for nearly 20 years. Tortillas, or omelets, stuffed with surprises like squid ink and blood sausage fill the bar counter, necessitating foldout tabletops and overflow seating across the aisle.
