We’ve written previously about the immense diversity of Mexican cooking: Every region has unique traditions that build upon ingredients common to much of the country. And yet there are a few regions that stand out for the variety and vividness of the flavors, colors and tastes found there.

Unless you know it’s there, you might miss this tiny shop hidden behind a bus stop on the outskirts of the northern Athenian suburb of Chalandri. Many Athens kiosks are twice, three times the size. But it’s certainly cozy, and once you’ve discovered it, you’ll keep going back, not just for the sweets – which would put a smile on the face of Scheherazade – but also for the spices, condiments, nuts, cardamom-perfumed coffee, arak and other hard-to-find Lebanese specialties, or maybe just to have a chat with the owner, Lina Tabbara.

Rio’s small traditional bars, known as botequins, are by definition simple establishments, where orders are usually taken down with pen and paper – and sometimes not taken down at all, but mentally noted. But even in these fuss-free eateries, times they are a-changin’.

Editor's Note: Sadly, this spot is now closed. The busy outer neighborhoods of Rio de Janeiro – locals refer to them as “suburbs,” though they are anything but – are full of old bars. Some of the best botequins (small, family-run establishments serving traditional food) have been kicking around in these parts for ages – but not all of them.

There is a certain rite of passage associated with being invited to dinner or coffee at a Greek friend’s house. Not so much because of what you will end up eating or drinking there, but because of what the other guests will be bringing as gifts. To most Western Europeans’ surprise, one of the most popular gifts for the host is a big dessert – the kind of cake that is usually reserved for birthdays or big celebrations in other countries. Greeks often arrive bearing big, rectangular patisserie boxes containing anything from a large cheesecake to ice cream- and sorbet-layered cakes. And of course, very often these boxes contain a pan of the Greek national dessert, galaktoboureko.

Early on in Jean-Pierre Jeunet’s 2001 film Amélie, the title character plunges her hand into a big sack of lentils, relishing the sensation of them slipping through her fingers, a look of pure pleasure on her face. That kind of behavior is verboten in shops that sell dry goods by weight, but buying groceries in bulk has its own inherent pleasures (and you can run your fingers through your purchases once you’re back at home). Just as with bulk wine, buying food in bulk is making a comeback in Barcelona. Not only does this practice yield less packaging waste, but in our minds, it also makes hunting for great ingredients all the more enjoyable.

We know that there’s a trend away from gluten and carbs these days, and all we have to say to that is: more for us! In Athens, bread and pies still form the foundation, if the not the substance, of many a meal – breakfast especially. Make like a local and start your day off right with cheese pie or koulouri from one of our top picks. (These places are also perfect for a pick-me-up later in the day.)

When we think of white wine in Catalonia, we think of its seemingly endless possibilities. Production of whites here has a 2,000-year-old history. The wide-ranging diversity in the area’s Mediterranean climate and calcareous soils, from the mountains to the sea, and the combination of old grape varieties and newly introduced “foreigners” with traditional and experimental methods of production make for innumerable styles and no taboos. Who knew white was a color with so many variations? The traditional Catalan grape varieties used to make white wine are mainly macabeo, xarel-lo, parellada and garnatxa blanca, but this area of Spain has the largest number of white grapes included in all its protected appellations (D.O.). Where other Spanish D.O.s usually are deeply defined by one or a few varieties, in the Catalunya D.O. there are more than 16 allowed – 35 counting the reds. In fact, this umbrella appellation, which covers wines that do not fall under the 10 subregion designations (Montsant, Penedès, etc.), was created to allow the use of all the grapes of the other Catalan designations in the entire area. It implicitly gives freedom to Catalan winemakers to express more than the old narrower conceptions of terroir and opens the doors to experimentation.

Dear Culinary Backstreets, I’ve noticed that a dish called “moustalevria” pops up in shops all over Athens in the autumn months. What is it, and where can I get it?

Dimitris Kotsaris was more proselytizer than baker. Rather than a flour-dusted apron, this mild-mannered gentleman would wear elegant suits to meet with journalists, bearing two or three kilos of his famous whole-wheat bread as a gift. He was an ardent believer in the medicinal qualities of bread and preached widely that good bread promoted good health, once even taking his case to Harvard, where he delivered a talk about the role of well-made loaves in healthy diets. In 1981 Kotsaris opened Pnyka, the pulpit from which he spread his yeasty gospel, and gave the bakery the Greek name for the hill downtown where, in the golden years of Ancient Greece, Athenians gathered for the general assemblies that played such a formative part in the creation of democracy. It is quite fitting then that the first Pnyka shop opened in Syntagma (“Constitution”) Square. The bakery has since added two more shops in the city, in Exarchia and in Pagrati, the headquarters of the operation, and its following is such that last year a third was established in Vienna. Kotsaris passed away last year but his vision lives on through his son George, who has taken over the business.

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!

It’s almost impossible to pass through Barcelona without setting foot in the Barrio Gótico, a warren of narrow, winding streets and medieval buildings that is the historic center of the old city. It’s also the epicenter of Barcelona’s tourist trade, which means that amongst all the Zara window displays, souvenir shops and tapas joints of questionable quality, it can be difficult to catch a glimpse of what the neighborhood once was. One lucky day, however, as we made our way through this touristic mishmash, we stumbled upon La Pineda, a true gem of old barrio authenticity.

Dear Culinary Backstreets, I’m traveling to Barcelona and I love visiting food markets. I’ve heard a lot about La Boquería, but are there any other markets that might be worth visiting?

There are places that have been around so long that they've become emblematic of a city’s entire eating culture. In Athens, Stani (meaning "sheepfold" or "barnyard," depending on your definition) is certainly one of them. It may have a rustic-sounding name, but this wonderful, old-fashioned dairy bar – in business since 1931 – is an urban fixture.
