Dear Culinary Backstreets, I keep hearing about the wonders of Cretan cuisine, but is it really any different from regular Greek cooking? And is there anywhere nice to try it in Athens?

In Spain, conservas, or foods preserved in cans and jars, are not simply a matter of economic survival or a source of basic nutrition for students, hikers, military recruits and the like. Rather, the tradition of conservas more resembles that of keeping one’s most beautiful jewelry locked safe in a strongbox, to be brought out only on special occasions like Christmas, birthdays or the victory of a favorite football team. There’s nothing better than some delicate canned cockles to lavish on your parents-in-law before a holiday meal!

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 second piece in our series featuring the hidden gems in some of Athens’ most touristy neighborhoods. We previously explored Psyri; it is now time to take on the holy grail of Athenian tourism: Plaka. There’s a reason why this area of old Athens, just below the Acropolis, is the city’s most touristy neighborhood: it has a history of more than 6,000 years.

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.

With the brutally forceful clearing of Gezi Park of its temporary inhabitants by Turkish police, the recent protests in Istanbul have lost the imposing physical presence that, incredibly, lasted for two weeks. These days, protestors are tossing ideas onto social media walls to see what might stick. To keep the resistance alive, we’ve been urged, via Facebook, to take part in all sorts of acts, passive and active, madcap and practical. But the one that really struck a chord with us is a campaign not to spend any money in shopping malls, not to even enter shopping malls, and to spend only what we must at small, local shops. Boycott the mall? Now, that’s a battle we’ve been waging since the late 1980s.

Editor’s note: While the fate of the Gezi Park occupation is being hotly discussed, we’ve been spending our time sipping deeper into Turkey’s other great debate: what is the country’s national drink? In the spirit of national reconciliation, here is our report. The recent protests that raged across Turkey may have been sparked by the government’s ham-fisted efforts to bulldoze a precious stand of trees in Istanbul’s Gezi Park, but the country’s eaters and drinkers had already gotten a taste of Ankara’s increasingly meddlesome overreach during the weeks and months before.

It’s not every day that you find a former national volleyball champ in the kitchen, but that’s just the case with Lu Dajie (aka “Big Sister” Lu) and her eponymous restaurants. After a successful career with the Chinese military’s volleyball team, followed by years working in restaurants for others, she left her hometown of Jianyang in Sichuan province with her brother, bringing her region’s famous cuisine with her. Now, in Shanghai, she is slowly building an empire.

Dear Culinary Backstreets, Where can I go in Barcelona when I'm tired of sightseeing and I just want to sit down and relax with a cup of coffee? Visiting museums and landmarks can be a lot of fun when you're a tourist but sometimes you can learn more about the life of a city by sitting in a chair in a café than you can by reading any guidebook. In Barcelona, there's no shortage of cafés but like anywhere else, it can sometimes be a bit tricky to find one that has just the right ambiance.

We generally prefer to keep our nose in a bowl of soup and out of the political arena, but over the weekend, Istanbul’s politics seeped through the cracks in our windows, in the form of teargas and general mayhem. As longtime foreign residents of Istanbul, we’ve found it relatively easy to steer clear of political activity, but every so often it barges into our homes and turns our stomachs.

To call someone a cachaceiro in Brazil is to deal a pretty low Portuguese blow. The word translates roughly to “drunkard” and evokes the image of an unkempt alcoholic clutching a plastic bottle of the powerful local liquor known as cachaça. It’s no coincidence that the name of the drink made with cachaça, the caipirinha, comes from the word caipira, roughly meaning “redneck” or “country.” That the national spirit is invoked in insults is emblematic of the poor image the drink has long had, but which has recently been changing. Like the newly assertive Brazil, the sugarcane-based alcohol is finding its way into chic circles where it was once seen as a bit cheap and rustic. In the past, a posh dinner host in Brazil would offer her guests a uisque (whiskey) or imported wine. But these days, it seems cariocas are finally embracing the truth: the caipirinha is a profoundly refreshing godsend on a steamy Rio summer night. A thriving cachaceiro scene is now budding both in Brazil and among a growing fan base abroad.

Editor’s note: As of this week, Rio de Janeiro joins Culinary Backstreets as our sixth city. We’re thrilled to have expanded to four continents, and are looking forward to sharing with readers our explorations of this exciting city's dynamic food scene. Like many things in Brazil's beachside, party-hard Carnival city of Rio de Janeiro, gastronomy has a hedonistic edge to it.

Editor’s note: This post wraps up our special series this week featuring our top street food picks in all of the Culinary Backstreets cities. As rapidly as Istanbul marches toward its modern destiny, street food in this city is still served the old-fashioned way, by boisterous ustas with a good pitch and, sometimes, a really good product.

Editor’s note: This is the fourth installment in our street food series this week, featuring dispatches on the best streetside eating in all the cities Culinary Backstreets covers. Before we get down to the business of discussing the best of Athens’ street food, a disclaimer: Athens is at a disadvantage when it comes to streetside eats. For one thing, a lot of venues – souvlaki joints, pizza parlors and even offal soup places – are open all night or even 24/7; they are just not serving on the street, though.

Editor’s note: This feature from Barcelona is the third installment in our series this week devoted to the top street foods in each of the Culinary Backstreets cities. In Barcelona, a great deal of eating is done in the streets. Sidewalk cafés line the plazas and paseos, often to the point that it’s difficult to tell which tables belong to which establishment.
