Sonoran Chicken with Nopales

This recipe makes use of nopales cooked sous vide—under vacuum, a technique from the professional kitchen that I’ve modified here for home cooks (see also Nopales en Bolso with Vegetables Escabeche, page 28). Nopales—cactus leaves—have a wonderful texture and fresh flavor almost like fresh green beans or green squash. In Mexico, they grow wild everywhere, available for the picking. The most amazing place to see nopales is at the central market of Mexico City, one of the truly great markets of the world. Arranged in circles are huge, round burlap bags, five feet tall by four feet wide. Each bag holds hundreds of nopales, and workers handle sixty to seventy-five bags simultaneously. Women whittle away at mountains of nopales with long, sharp knives, trimming off their sharp spines in seconds while gossiping with their neighbors, stopping only to sell to shoppers. The enormous amount of nopales sold underscores how important they are to the daily diet.
