The holiday season is one of the more subdued times of the year in Mexico City. Many people leave the city for vacation or to visit family and friends in other parts of the country. We, however, tend to stick around more often than not, traveling around the city and enjoying the relative peace. That’s how we happened upon Coox Hanal, a restaurant hidden inside a century-old building in the Centro Histórico that specializes in the cuisine of the Yucatán, the peninsula that juts out into the Gulf of Mexico and the Caribbean Sea like a hitchhiker’s thumb.

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.

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.
