The sap of the spiky maguey plant has long been used by the indigenous peoples of Mexico to prepare pulque, a milk-colored, viscous drink that has roughly the same alcohol content as beer. When they arrived in Mexico, the Spanish were introduced to pulque. Used to imbibing harder stuff, however, the conquistadors experimented with distilling a mash made out of the maguey plant, in the process inventing the beguiling spirit known as mezcal. Previously a liquor considered the province of the poor and working classes, mezcal has in recent years become one of the trendiest and most popular alcoholic drinks in Mexico, with more than 150 different brands now on the market. (Tequila, made from blue agave – a kind of maguey – and produced within a specific region of Mexico, is the best-known member of the mezcal family.) The rise in mezcal’s popularity has led to a proliferation of mezcalerías, wine bar-like spots that specialize in pouring the drink. In Mexico City in particular, mezcalerías have popped up in nearly every neighborhood, and their numbers keep growing.

In the world of chicken breast pudding (a traditional Turkish dessert made with thickened milk and thin strands of poached poultry), elasticity is the quality that the confection is judged upon above all else. Tucking into a real tavuk göğsü requires full concentration, a good bit of dexterity and the proper tool. A special spoon with a flat chopping nose – much like a spade – was designed just to deal with the situation and, as far as we know, this utensil is found exclusively in Turkish pudding shops. So when we got a tip about a muhallebici where “the tavuk göğsü stretches off the spoon much farther than you could fathom,” we knew we’d be dealing with the genuine article.

Dear Culinary Backstreets, We will be visiting Barcelona with our children. Do you have any good recommendations of places in the city to eat with kids?

While the Princes’ Islands make for a great escape from the city, it used to be hard to think of them as a culinary destination. That is, until Heyamola Ada Lokantası opened. The restaurant is a perfect storm of inspired food, chill ambiance and small-label Turkish wines, all at ridiculously low prices.

Once a resort town on the outskirts of the Greek capital, Phaleron – only a few miles from downtown Athens – is now well incorporated into the city’s urban fabric. The area has remained an upscale neighborhood, but, sadly, it has lost its distinctive character: the sea is now polluted, the open-air cinemas have been turned into parking lots, and many of the stately mansions were demolished to make way for apartment blocks during the construction boom of the 1960s.

Editor’s note: This is the penultimate installment of “Best Bites of 2012,” a roundup of our top culinary experiences over the last year. Stay tuned for our final “Best Bites” dispatch, from Istanbul, tomorrow. Restaurant Roma We hadn’t planned on bringing in La Nochevieja at Restaurant Roma, but it was nearby and we didn’t feel up for public-transport adventures on New Year’s Eve. Situated on a quiet street in the upscale but untouristy Barcelona neighborhood of Sant Gervasi, Roma is thoroughly nondescript – a neighborhood joint frequented by neighborhood people of a certain age. The wood-paneled walls, racks of Maxim magazines and TV mounted in the corner kept our expectations pretty low.

Mexico City is probably not the first place one thinks of when it comes to ice cream. Enchiladas and tacos, sure, but ice cream? In fact, the city has quite an established ice cream scene, with spots in nearly every neighborhood. La Especial de París, an ice cream parlor on the edge of Colonia San Rafael, stands out as a family-owned venue that – unlike many of its competitors, which have increasingly turned to selling mass-produced dairy products – still makes all its ice cream the old-fashioned way, by hand and with fresh, all-natural ingredients.

It is hard to identify exactly when the forgotten neck of Istanbul between Etiler and Arnavutköy became prime real estate. Not so long ago, overgrown green space alongside the road was interrupted by the occasional car wash and low-slung shanty; it was not so much a place as a road to other places. But now it seems this road is going places of its own. A private tennis club with a swimming pool shares a parking lot with Backyard, a café and restaurant with a big grassy yard filled with lounging parents and children wallowing in that rare Istanbul commodity: grass.

We can’t prove it, but we suspect a network of tunnels lies underground in Beyoğlu that connects most of the meyhanes of Asmalımescit and Nevizade Sokak to the same mediocre kitchen, resulting in unexceptional mezes at scores of venues in this dining district. Following a number of tips, our search for a standout meyhane led us to the unassuming Asmalı Cavit on Asmalımescit Caddesi, where we’ve consistently had outstanding food. This traditional meyhane bucks the trend toward mediocrity with subtle but significant tweaks that, for us, make the meal.

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.

The arrival of fall always finds us heading instinctively, like salmon swimming towards their ancestral headwaters, to the Balık Pazarı, Beyoğlu’s historic fish market. Autumn is quince season in Turkey and that means the appearance – for a limited time only – of one of our favorite desserts, ayva tatlısı (literally meaning “quince dessert,” although “quince in syrup” might be more accurate). Nestled in the fish market is Sakarya Tatlıcısı, a pastry and sweets shop with old-world charm that is one of our top stops for this dessert. The apple-like quince is one of those complicated, mysterious fruits that take on a new life when cooked. Raw, quinces are often astringent and inedible.

The large banner in La Nena chocolatería proclaiming “No Hay Alcohol” (strung up between a rocking horse and a wooden toy kitchen) makes it fairly clear that this is not a place for sophisticated conversation and cocktails. That doesn’t mean that La Nena (which means “The Girl” in Catalan) doesn’t cater to any other vices. Indeed, its delicious homemade cakes, pastries, hot chocolates and savory snacks tempt the residents of Barcelona’s Gràcia neighborhood on a daily basis.
