Dear Culinary Backstreets, I’ll be in Spain during the December holidays and I’m wondering if Barcelonans eat any special meal on Christmas? If so, what is it and where in the city could I try it?

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.
