Just a block away from Mexico City’s financial district, one unlikely food star sets up shop every morning. From Monday to Saturday, at La Abuela, 72-year-old Arnulfo Serafin Hernandéz feeds hungry office workers, commuters, neighbors, school kids, government officials and tourists from all over the world with one of the simplest Mexican dishes: tacos de canasta.

Editor's note: For our last stop on CB's Global Bar Crawl this week, we're pulling up a stool at our favorite mezcal bars in Mexico City, kicking back and savoring every last drop. Para todo mal, mezcal. Para todo bien, también. Y si no tiene remedio, tómate litro y medio. For everything bad, mezcal. For everything good, the same. And if that doesn’t help, drink a liter and a half. – Popular saying among mezcal lovers.

Fried tortillas, stuffed and sauced: enchiladas are simple in concept, but they come in a seemingly endless variety, depending on region and ingredients. The tortillas might be made of corn or wheat flour, and they could be stuffed with all manner of meat or vegetables (or both), but the sauce – or salsa – is really what it all comes down to.

Once considered Mexico City’s next hot neighborhood, Santa María la Ribera, near the city's center and one of its first suburbs, has been slow to deliver on that promise. While neighborhoods just to the south have stolen Santa María’s thunder, it’s finally showing signs of life – one of which is the restaurant/cooking school La Casona del Sabor. Built 140 years ago by a German immigrant couple, the building that houses La Casona features traditional colonial architecture, including a grand entrance that leads into a spacious, landscaped courtyard. Looking out over the courtyard is a colorfully tiled verandah that connects to multiple rooms. Once family quarters, these rooms now serve the culinary school. The school's head chef, Jorge Luiz Alvarez, began the school seven years ago in his nearby apartment, but when space became tight, he took over the house and expanded the business.

Making mixiote takes some effort. On its home turf in Central Mexico, the dish is made by taking chicken, beef or mutton that is seasoned with pasilla and guajillo chili peppers as well as flavorings like thyme, cumin, bay leaves, oregano, onion and garlic, wrapping it in individual portions in maguey leaves and then slow-cooking the bundle in a pit, preferably overnight. But how about in Mexico City, a crowded metropolis where it’s not always possible to build a BBQ pit in the ground, or to obtain maguey leaves, which are both expensive and difficult to work with?

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.

In Mexican cuisine, sweets are for the most part simple treats that are enjoyed at the park, market or beach, such as caramelized fruits and vegetables, blocks of nuts or amaranth seeds held together with honey, or small rice paper cakes filled with honey. The common denominator of most of these sweets is their simplicity. When it comes to ice cream and other frozen delights, however, the country truly shines, with an astounding variety of cold treats to please sweet tooths of every persuasion.

Editor’s note: This feature from Mexico City is the second installment in our street food series this week, highlighting the best streetside eats in each of the cities Culinary Backstreets covers. 1: Pambazos The pambazo is a Mexican sandwich that’s similar in style to the more familiar torta, but not nearly as ubiquitous. Most commonly found at weekly street markets like Sullivan, pambazos are made with hard, white bread rolls soaked in guajillo chili sauce that softens the crust and gives it a warm, orange-red hue. Once dried, the bread is sliced in half and then filled with a generous portion of diced potatoes, chorizo, lettuce, sour cream and sprinkled queso fresco. The bread is quite fragile, so eating the concoction can be somewhat challenging. From the first bite the pambazo starts to disintegrate, and by the end we’re usually scooping up the heavy mess with our fingers. It’s all worth it, though, as the light hint of chili in the bread and the hearty ingredients inside give the dish the same satisfying and belly-filling pleasure that comes with a good bowl of thick stew.
