Pickled honeydew may sound like an odd arrangement, but it's surprisingly delicious, and among the vast array of pickled treats one can sample on our Two Markets, Two Continents walk in Istanbul.

When Liz Hillbruner moved to Mexico City in 2010 from the United States, she found herself obsessed with tlacoyos, the little football-shaped street eats she saw cooking on griddles around her neighborhood. They were a perfect package of corn dough, wrapped around beans or cheese. As she ate her way through the neighborhood, she simultaneously enrolled in a master course on Mexican cuisine. When it came time to formulate a final project, it seemed only natural to study what was already on her mind. She decided on a map – the Tlacoyografía – a tool for the community and street food-loving transplants to find all the tlacoyo stands in the tlacoyo paradise that is the San Rafael neighborhood.

The vendor at this hole in the wall in Mexico City is selling tacos de canasta, cheap and filling tacos that are steamed inside a basket (hence the name, ‘canasta’ means ‘basket’), to customers. They make a quick and delicious lunch.

Our Barcelona bodega walk kicks off with a carajillo, coffee spiked with a shot of Catalan brandy. It's the best way to start a day of casual imbibing at some of the city's most iconic bodegas. 

The consumption of sake is a sacrosanct affair in Japan. In Japanese, the term “sake” technically denotes all alcohol, though it is often used interchangeably with the less ambiguous “nihonshu.” The true genesis of the island nation’s archetypal brew is lost to time, though the divine concoction of water, rice, yeast and koji mold likely originated, or at least became more standardized, sometime during the Nara period (710-784 AD) when Empress Genmei consolidated rule over an agrarian society. Most people in this fledgling nation state participated in animistic and ancestral folk worship, within which rice, and by extension nihonshu, came to play important ritualistic roles.

Stretched to translucence by a series of acrobatic, table-slapping wrist flips, then stretched just a bit further until it seemingly must tear under its own weight, the palata dough passes from the hands of Myo Lin Thway. In a moment, other hands take over. Perhaps they fill it with minced spiced chicken, for keema palata, or perhaps they fold it instead into an empty square, soon to be the conveyance for masala-red curry. After a brief interlude at the griddle, the flaky flatbread is surrendered to still other, hungrier hands. Myo, in the meantime, has swirled a little oil on his tabletop and patted down another wad of dough, pressing it wider and flatter until it, too, can take to the air.

We spotted this colorful display of conservas (canned fish) at one of Lisbon’s finest traditional markets. The tinned fish industry is an old one in Portugal, dating back to the 19th century. The quality of the fish and the olive oil, plus the retro packaging makes it a delicious souvenir or gift.

We spied a burst of green – different varieties of cilantro as well as other herbs – on our Queens walk. While the borough doesn’t have the same large markets as some of the other cities we operate in, you can still find plenty of smaller fruit and vegetable stands sprinkled throughout the area.

If you hadn’t read the flyer closely before heading to Shanghai’s first ever MeatFest last month, you might have been a bit disappointed upon arrival. The sounds and smells of sizzling meat might have seemed like a carnivore’s dream come true, but the name was tongue in cheek; the event was thrown by Vegans of Shanghai for “eco-conscious meat lovers” and served only domestically sourced plant-based “meat” products. It’s part of a bigger push towards eating a plant-based diet in China, where vegetarians make up less than 5% of the population. But even at such a low rate, that still comes out to approximately 50 million people (a population larger than that of Spain). Historically vegetarianism is rooted in Buddhist or Taoist beliefs but, like recently in the West, the meat-free lifestyle in China has become less about religion and more focused on health and being environmentally friendly – and millennials are leading the pack.

Loukoumades are considered to be one of the oldest recorded pastries (and desserts, for that matter) in the world – in fact, the ancient Greek poet Callimachus and philosopher Aristotle wrote about them. Nowadays, these photogenic fried-dough balls are particularly Instagram-worthy. Snap your photo before they get gobbled up!

Come summertime, Carmine, a street vendor for all seasons, prepares refreshing granita on Via dei Tribunali in Naples. The semi-frozen dessert made from sugar, water and various flavorings, counters the oppressive heat. Don’t leave before exchanging a few words with Carmine, who is renowned for his ability to strike up a conversation with anyone.

Guda cheese is sheep cheese from eastern Georgia, aged in guda, which is sheep skin. Nowadays most guda is aged in plastic, but we found one vendor at the Deserter’s Bazaar who has the real deal in her stall, which comes from Tusheti in the high Caucasus.

An aguas frescas vendor in the Xochimilco market stands at the ready behind his offerings: there were over a dozen different flavors on the day we visited. He served us an incredible lemonade with chia seeds, a very traditional (and delicious) pairing.

Sweet, fluffy and incredibly habit forming, yakiimo (roasted sweet potatoes) are an autumnal treat loved throughout Japan. But in a small corner of Setagaya, Tokyo’s largest ward, a dedicated shop bakes them year-round. Kept busy by a steady stream of visitors, all clutching tell-tale paper bags, Fuji has a national take on a traditional snack. The slow-baked yakiimo are often sold from slow-moving mini trucks equipped with onboard wood-burning ovens. As the trucks roll by, they fill the air with both a comforting smell and familiar song. Roasted on a bed of stones, the potatoes are commonly known as ishiyaki imo and once saved Japan from famine when rice crops failed in the 18th century. Served without butter or salt, it may seem a little simple to the untrained eye, but cooked right, the flavor and texture render any additions entirely obsolete.

While the word yakitori translates to “grilled chicken,” it can refer to any kind of grilled, skewered food,  all of which are cooked slowly over charcoal. On our Tokyo Time Machine culinary walk, we explore this among many other specialties.
