Caldo Tlalpeño Capitalino

This caldo is from Tlalpan, the old volcanic borough in the south of Ciudad de México, and the name carries the neighborhood the way pozole carries Jalisco. The story most capitalinos repeat is that the dish was invented in the cantinas of Tlalpan a century ago, served to men who needed something restorative between rounds of pulque. Whether the cantina version is true or apocryphal, the caldo settled into the home kitchens of the city and never left. This is comida casera. Weeknight food. The kind of soup a mother in Roma or Coyoacan makes when somebody is tired or somebody is sick or somebody just came in from the rain.

What makes caldo tlalpeño tlalpeño and not just chicken soup is the chipotle and the epazote. Two ingredients. Both pre-Columbian. The chipotle gives it the smoky depth that separates this caldo from the watery broths people pass off as Mexican chicken soup outside Mexico. The epazote, torn in at the end, gives it the herbaceous note that no other herb can replace. Cilantro is not a substitute. Oregano is not a substitute. If you cannot find fresh epazote, leave it out and call the soup something else. Esto no es comida de un solo México, but it is comida capitalina, and the herb is not negotiable.

The garbanzo is what makes it filling. The zanahoria, calabacita, and chayote are what make it a complete meal in one pot. The avocado, queso fresco, and lime at the table are what make it caldo tlalpeño and not generic chicken stew. Each diner finishes their own bowl. That is the ritual. My mother's notebook has a page for this caldo, written in pencil with the margin note 'más chipotle del que crees,' more chipotle than you think. She was right. Saber cocinar es saber vivir.
