La Boquería is undoubtedly one of the most famous markets in the world, but there are 43 markets spread across Barcelona, each with its own unique charms. Once a year, they can be experienced all at the same time, in the same place. From October 17 to 19, 265,000 visitors thronged the square in front of Barcelona Cathedral for the fifth edition of the Mercat de Mercats (Market of Markets) festival, which gathered 40 stalls, 30 local artisan producers, 40 chefs with 17 Michelin stars between them and 14 of the city’s best restaurants. The festival offers an amazing opportunity for locals and tourists to taste the dazzling array of Catalan flavors and to get to know the city’s neighborhood markets.

Let us begin with a little Greek mythology. Hermes – son of Zeus, god of thieves and commerce and messenger of Olympus – and Krokos, a mortal youth, were best friends. One day, while the two friends were practicing their discus throwing, Hermes accidentally hit Crocus on the head and wounded him fatally. On the very spot where he was felled, a beautiful flower sprang up. Three drops of blood from Krokos’s head fell on the center of the flower, from which three stigmas grew. This is just one of many origin stories for Crocus sativus, or the saffron crocus, whose crimson stigmas are harvested to make the highly prized spice of the same name.

Shanghai offers a huge range of dining at every price point imaginable. Fortunately for us, cost is not necessarily commensurate with quality in this town; you don’t have to break the bank to eat well. In fact, some of our favorite eateries offer bargain set lunches. Mi Xiang Yuan Hidden down an alley, Mi Xiang Yuan, a Shanghainese joint owned by a local celebrity chef and his family, serves affordable set lunches that bring in the crowds. Try their marinated pork rice bowl (卤肉饭, lǔròu fàn) or "lion’s head meatballs" (蛤蜊牛蒡肉圆套餐, gélí niúbàng ròu yuán tàocān), and you’ll also get a side of soup, tofu and vegetables of the day plus a bowl of rice, all for less than 30 RMB ($5), no matter which benbang main you try. You can’t beat that price in the Xintiandi neighborhood.

Horn of plenty, yellow foot, ox tongue, gray knight: the bewitching names are like something out of a fairy tale. But at Casa Lucio, in Sant Antoni, these are all mushrooms you might find on your plate, especially in autumn.

Editor's note: We're celebrating Mushroom Week at Culinary Backstreets, and today's installment takes us to Istanbul's Belgrade Forest, where Turkey's leading wild mushroom expert has found some remarkable fungus specimens.

It’s October and mushroom season in many parts of Europe, but if you were hoping for anything like Genoa’s Porcini Festival in Athens, you’re out of luck. But don’t despair: ‘shrooms, wild and cultivated, can be found; it just takes a little sleuthing.

In Mexico, the land of eternal spring, something good to eat is always in season. We ravenously await the arrival of artichokes in March, mangos in April, fresh corn in September. Even the wriggly little gusanos de maguey (maguey worms) which appear in May are wildly anticipated – by some. Change in season is subtle here, but essential to the survival of the country. But seasonal lines are blurring. Asparagus rears its tasteless Chilean head all year; pallid strawberries are found in December. Seasons have gone global and our palates suffer for it. Which is all the more reason to pay attention to what’s local now. From July into October, coinciding with our temporada de lluvia, wild mushrooms, spurred on by rain and humidity, hit the markets of central Mexico. Here in the capital, the month of August is high ‘shroom time.

Whether we’re talking fat-free, gluten-free, organic, MSG-free, Paleo or vegetarian, every regimen takes on new challenges and pitfalls when you are traveling or living abroad – especially in a country like China, where you may face a language barrier.

Anyone looking for a bit of entertainment or foodie satisfaction while on a layover in Shanghai will need to look well beyond the confines of the airport. Pudong’s international airport may be a huge, mostly gleaming, modern space, but it has some of the most overpriced, bland food and off-brand shopping with little to do beyond making repeated attempts to connect to the free Wi-Fi.

“We grow everything here – kale, dill, peppers, cucumbers, tomatoes, arugula, eggplant, lettuce, cauliflower… everything,” the elderly woman says proudly, waving her hand in the direction of her small field as she digs her worn plastic sandals into the dirt. While she grows the vegetables and herbs, her 80-year-old husband tends his pomegranate trees and takes their products from this patch of farmland at the far northern end of Istanbul’s Sarıyer district to sell at local markets around the city.

When we pick up a hefty, shiny copper pan in his workshop, Emir Ali Enç unhesitatingly claims, “You are now holding the best saucepan in the world.”

Gnarled evergreen mastiha (mastic) trees cling to terraced hillsides throughout the southern part of Chios, a Greek island in the Aegean. These humble trees (Pistacia lentiscus var. chia) have been fought over and cherished for thousands of years because they produce “tears” of delicious and healing sap. The best pharmacists in ancient times used to concoct luxurious healing balms with mastiha sap; Emperor Justinian’s personal physician mixed mastiha and deer brains to make a beauty cream. We haven’t tried that recipe yet.

[Editor's note: We're sorry to report that Harbin Dumplings has closed.] Walk along just about any street in Shanghai these days, and you’ll see an ever-encroaching range of Western brands, standardized brand signage and food franchises. As in other rapidly developing countries, the battle for consumer dollars and brand loyalty has meant more chains and mass-produced food. That’s partly what makes stepping into one of the several Liu Family Harbin Dumplings shops a breath of fresh air. Every morning until the lunch rush, the dining room and back rooms are set up with trays and workers dexterously making every dumpling from start to finish. Dumpling wrappers are meticulously hand-rolled, the fillings are mixed in large batches, and the time-consuming process of filling and closing the dumplings marches on until tray upon tray is ready for boiling – but not until they’re ordered during the lunch rush.

[Editor's note: we're sorry to report that Butifarring is now closed.] Gourmet fast food has swept through Spain at full speed. It comes in multiregional styles and with strong creative inspiration behind it – and, most importantly, the food itself can be exceptional.Eric Camp, Albert Gómez and their three partners are a good example of this, with their sausage-centric project, Butifarring, and their first small venue in Barrio Gòtico, which is much more than a Catalan hot dog or sandwich place.

A few weeks ago we wanted to get out of bustling Mexico City, but we only had one day free, so we decided to look for a place where we could see some sights, eat, enjoy ourselves and still be back before the day was over. We found not just one, but two gorgeous towns that fit the bill in the state of Hidalgo, just over an hour north of Mexico City. The picturesque town of Real del Monte, also known as Mineral del Monte, is a small pueblo mágico (the Ministry of Tourism’s designation for a unique and historically significant village) with a long and rich heritage. It was one of the first mining towns the Spanish established after La Conquista. Much of the silver and gold mined during the colonial and post-colonial periods came from this part of the country.
