“I’m a vegetarian – what will I eat in Mexico other than beans and rice?” Taco-madness has so consumed the world’s view of Mexican cuisine that the traditional mainstays of the diet often don’t get the billing they deserve. Beans, corn, squash, chilies and tomatoes are grown together in milpa farms – a biodynamic system of agriculture. Anyone who has ever grown anything knows: if you let a garden grow naturally, you’ll have an abundance of leafy greens that most of us call “weeds.” Well, in Mexico, nothing edible goes to waste. Just as every bit of meat from an animal is used, so are those weeds and all the other tender leafy bits.

The typical Neapolitan breakfast is fast, often consumed standing at the espresso bar. A croissant and a quick coffee – and, boom, the day begins. Many people in the English-speaking world, however, will use coffee bars and cafès as a place to relax or work. They bring computers, connect to the Wi-Fi and, ordering just one coffee, may even sit for hours. Three years ago, a group of entrepreneurs decided it was time Naples had a bar where people could indulge in a lazy morning breakfast, a slow midday meal or a long afternoon tea – a place where the chairs are comfortable, the tables are an inviting wood and you are encouraged to stay and make your phone calls, write your papers and chat with friends.

A neighborhood on the southeast side of Filopappou Hill, between Acropolis, Petralona, Kallithea and Neos Kosmos, Koukaki was named after one of its first residents, Georgios Koukakis, who in the early 20th century opened a successful factory there manufacturing iron beds. Gradually the area developed into a charming middle-class neighborhood, full of life and – up until the 1980s – a place Athenians charmingly referred to as “Little Paris,” in large part because of its bohemian vibe. The lower side of Koukaki has long been a students’ area due to the nearby Panteion University. Rents used to be relatively low, but after the opening of the new Acropolis Museum in 2009, the surrounding area has been booming, growing into an Airbnb goldmine and turning many locals against the trend.

The Algarve, one of the most visited regions in Portugal, also has some of the country’s most distinctive and delicious cooking. Integrating layers of different historical influences, from the Romans to the Moors, along with fishing traditions and countryside rusticity powered by its fertile land, the Algarve has made a deep impression on Portugal. But until Taberna Albricoque came on the scene, the region hadn’t been making much of an impact on Lisbon menus. Bringing the Algarve’s history to the forefront of Lisbon dining was one of the goals of chef Bertílio Gomes in opening his new restaurant. Albricoque, in fact, is the word for apricot in the Algarve, notable because the south has preserved its Arab etymology, as elsewhere in the country damasco is used (instead associating the fruit with the city of Damascus).

Dear Culinary Backstreets, I’ve heard about drinks in Mexico called “aguas frescas,” but what exactly are they? Visitors to Mexico are sure to encounter aguas frescas, a popular category of drinks that are ubiquitous at food stands and eateries around the country. These colorful beverages, whose name literally means “fresh waters,” come in a variety of different flavors depending on the main ingredient, but generally all are made by mixing a fruit juice with water and sugar.

Ask any former resident of the Balkans now living in New York where they buy the flaky, savory phyllo pie known as burek, and they may very well direct you to Djerdan Burek in Astoria. Burek (also known as börek) is a staple eaten in many forms throughout the regions that once formed the Ottoman Empire. In New York City, though, most purveyors of burek come from Albania and Bosnia, and if you’ve ever ordered a slice of burek at one of the many Albanian-run pizzerias in the Tri-State area, there’s a good chance it was baked by Djerdan as well. Their Queens storefront is a homey sit-down eatery doling out plates of meaty stuffed cabbage and grilled Balkan sausages, but Djerdan is especially well-known among immigrants from former Yugoslavia for being the only Balkan burek factory in the United States.

When it comes to the first meal of the day in Beşiktaş, it’s hard to replace the institution that was Pando’s lovely old kaymak shop. Yet as much as Pando was the neighborhood’s culinary standard-bearer, another side of breakfast in Beşiktaş has emerged in the last five or so years, a side that feels more contemporary, more real and – somehow – even more “Beşiktaş.” After being tipped off long ago, by 2013 we finally came to appreciate the simple charms of Çakmak Kahvaltı Salonu, which is currently swimming in a sea of breakfast cafes that align Istanbul's now infamous Kahvaltıcılar Sokağı. Beşiktaş is a large district in central Istanbul with an equally large and varied population, but at its commercial center, the çarşı (market), there is a coherent feeling of local identity. The neighborhood’s sometime champion soccer team is certainly a unifying force, as is the underdog political party (CHP) that remains popular, but the “Beşiktaş type” can’t be reduced to simple affiliations.

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.

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.

Growing up in Athens in the 1980s and 90s, weekend family excursions to a suburban taverna were an integral part of life. Back then, prices were affordable and eating out was not a luxury; in fact, it was a social necessity. It was a way to catch up with friends, enjoy good food and good wine, but also to entertain the kids. These tavernas were often away from the city center, in areas that offered a break from the gray buildings and the heat – usually with a large outdoor area shaded by trees, encompassing a playground and sometimes even a pond with small boats to enterain the kids. The food on offer was basic, but delicious – mainly meat (grilled lamb chops, etc.), salads, fried vegetables (zucchini, eggplant, potatoes) and dips (tzatziki and tyrokafteri, a spicy feta spread).

Athens, unofficially known as the Big Olive, has many delightful spots for a picnic in all seasons. Okay, in summer perhaps you’d rather be on the beach – and that can be arranged if you hop on a bus or tram for the southern coastal suburbs of Voula, Vouliagmeni and Varkiza – but in the city proper you can spread your meal on a hillside with a view of the Acropolis. With the weather often sunny and mild even in February, all you need is a little DIY initiative and the ability to resist the temptation of a snack at one of the many “fastfoodadika” or a sit-down meal in an air-conditioned taverna.

In a 2003 TV commercial for Cola Turka, the actor Chevy Chase was seen speaking Turkish and then sporting a moustache, after taking just one sip of the intended challenger of Coke in this country. This sensational ad – which riffed on the old theme of American cultural imperialism through its number-one agent, Coca-Cola – was the first time that Turkish soft drinks caught our attention. Though we didn’t take to the overly sweet Cola Turka, we did start looking beyond, to its local brethren in the market: gazoz, a world of nearly extinct Turkish carbonated drink brands with a fanatical following.

The Neapolitan stairs are ancient urban routes that connect the upper city (the Vomero district) to the lower city (the historic center). The most famous of these stairs is the Pedamentina di San Martino, a staircase of 414 steps dating back to the 14th century, which starts from the old center and reaches the Castel Sant’Elmo, on the Vomero hill. Along the way there are beautiful panoramic views of Naples. One reason to walk these Neapolitan stairs (besides the views) is to look for Totò Eduardo E Pasta E Fagioli, an old tavern with an amazing terrace overlooking historic Naples. The name is dedicated to two great masters of Neapolitan theater and cinema: Totò (Antonio de Curtis) and Eduardo de Filippo.

The rustic Neapolitan tarallo, made of 'nzogna (lard), pepper and toasted almonds, is a true delicacy. It can be considered the first popular snack in Naples, a bite that combines the punch of black pepper with the sweetness of almonds, the whole united by lard. It’s a dangerous combination for the waistline, that’s for sure. Taralli are offered to celebrate a new home, shared with friends during soccer matches, enjoyed with one’s significant other on the rocky shore, given to guests at parties, taken aboard boats (it’s the very height of yuppiness to eat them accompanied by iced spumante while out at sea). Until a few years ago, taralli were sold by tarallers, roving vendors who carried a basket full of taralli on their heads.
