Nopales are the tender, fleshy cladodes of certain Opuntia prickly-pear cacti, harvested young and consumed as a vegetable in Mexican and Southwestern U.S. cuisines. They have a mildly tart, green-bean-like flavor and a characteristic mucilaginous texture when cooked.
History & Origins
Nopales have been gathered and cultivated in central Mexico since at least the Aztec period, when they formed a dietary cornerstone alongside maize, beans, and chiles. After the Spanish conquest, the plants spread across the Mediterranean and were eventually naturalized in arid regions from South Africa to India. Mexico remains the world's foremost producer and consumer, where nopalitos appear in both traditional cookery and modern health-food products.
