Editor's note: This week, Mexico City joins Culinary Backstreets as our fifth city. We're delighted to launch Culinary Backstreets: Mexico City and look forward to sharing our culinary discoveries in this captivating metropolis. The vast megalopolis of Mexico City is one of the most misunderstood and misrepresented cities in the world. Adventurous tourists are often surprised to discover a vibrant national capital filled with incredible architecture, beautiful weather and amazing food. In some ways, this scene has been playing out for 500 years.

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.
