Editor’s note: This post was written by “Meliz,” an intrepid explorer of Istanbul’s culinary backstreets and frequent Istanbul guest contributor who would like to keep her anonymity. It all started with Laz böreği. It was not just any Laz böreği that showed up at the dinner party that evening, but perfect Laz böreği: layers of yufka (phyllo), buttery and moist, dusted with confectioner’s sugar, in a symbiotic balance with the custard, which was neither too sweet, nor too eggy, neither too runny, nor too stiff. Juuuust right. Goldilocks would have been proud. And, it turns out, this stuff is addictive.

The Praça da Bandeira, an area of Rio that until recent years was mostly known for prostitution and cheap inner-city housing, is rapidly changing. Lying in the shadow of the massive Maracanã Stadium – built for the 1950 World Cup and the planned location of the opening ceremony of the 2016 Summer Olympics – it is alive with new construction and pedestrian traffic, which are changing the tired face of this historical but underappreciated neighborhood. And sitting snugly in the midst of this new buzz is Aconchego Carioca, a restaurant and bar with one of the best beer menus in Rio.

Editor’s note: This is the fourth installment of “Spring (Food) Break 2013,” featuring our favorite foods of the spring season in each city Culinary Backstreets covers. This year’s Nevruz celebration, an ancient welcoming of spring, may be remembered for its political significance in which a peace deal was struck between Turkish leaders and Kurdish rebels. But once the shoulder-shrugging, line-dancing, fire-jumping and ululating are over, the real bounty of the season will continue to be celebrated all over Turkey and in many Istanbul restaurants, from the chic to the shabby.

Dear Culinary Backstreets, We’ll be visiting Mexico City and are wondering about the organic food scene. Will it be easy for us to find organic produce? How can we know whether or not something we’re buying is really organic?

The first wave of Indian, Pakistani and Bangladeshi immigrants arrived in Athens in the early 2000s, bringing a new eating culture with them. This was a time of prosperity in Greece and consequently the first South Asian restaurants, such as the now-defunct Pak Indian, were welcomed with open arms by Greeks who were willing to experiment. It helped that an enormous number of young Greeks had studied abroad in the 1990s and early 2000s, mainly in the United Kingdom, where they were introduced to the cuisine of the Subcontinent.

As the legend goes, a 19th-century Catalan farmer was out experimenting in his fields when he came up with a new kind of longer, juicier green onion, the calçot. In creating the onion, the farmer produced much more than a new vegetable; he also paved the way for the rise of an idiosyncratic, and distinctly Catalan, cultural event.

Dear Culinary Backstreets, In just about every restaurant or bar I’ve been to in Barcelona, I’ve seen a dish called “tortilla.” What exactly is a tortilla and can you recommend any places where they are done especially well? Although it would seem that much of the world imagines the inhabitants of Spain subsisting largely on paella, the truth of the matter is that it is the tortilla española, also known as tortilla de patatas (truita de patata in Catalan), that  really holds the place of honor in the hearts and stomachs of Spaniards. Often translated into English on menus as “potato omelet,” this hearty round cake of potatoes, eggs, olive oil and salt has nothing to do with the traditional French omelet, nor does it have anything in common with a Mexican tortilla. At its most basic, the Spanish tortilla is made by frying up a thick mass of sliced potatoes and eggs in olive oil and then slicing it into savory wedges.

Markets in Mexico City are as integral a part of the culture as mariachi music and tacos, providing a place for neighbors to come together for shopping, gossip and family outings and playing a key role in keeping the social fabric tightly woven. While most neighborhoods have their own brick-and-mortar locations, their street markets are far more colorful. These crowded, boisterous shopping areas – some so large that their colorful tarp roofs can been seen on satellite photographs, stretching for miles – are also an essential component of the city’s culinary scene.

Dear Culinary Backstreets, I’ll have an eight-hour layover in Istanbul and was wondering if you have any suggestions for places to go for a good Turkish breakfast and lunch. I love to eat at small, local places serving authentic food. I would prefer restaurants in the Yeşilköy area, as I have to be back at Atatürk Airport to board an international flight (which I cannot afford to miss!).

Editor’s note: This post is the first installment of “Best Bites of 2012,” a roundup of our top culinary experiences over the last year. Stay tuned throughout this week for “Best Bites” from all of the cities Culinary Backstreets covers. Hai Di Lao Hot Pot Restaurant We’re usually loathe to mention a restaurant that has locations all around China, but we were blown away by the dedication to customer service here – something that is sorely lacking in China. Too often, it’s a choice between authentic flavors or service. Not at Hai Di Lao.

From a country that maintains a “national strategic pork reserve” – vast bunkers of frozen meat that can be released when the price of the commodity gets too high – one might not expect to find an impressive number of traditional vegetarian restaurants, but you’d be surprised. While exact numbers are hard to pin down in China, it is thought that around 20 percent of the Chinese consider themselves Buddhist, a number that tops out at around 280 million people. In culinary terms, that translates to hundreds of millions of would-be vegetarians – though, as in any religion, devotees interpret tenets at will, and most “vegetarians” in China enjoy a sprinkling of pork in their tofu to “add flavor.”
