Cactus [SEP] Food
The fruit of the saguaro ("Carnegiea gigantea") has long been important to the indigenous peoples of northwestern Mexico and the southwestern United States, including the Sonoran Desert. It can be preserved by boiling to produce syrup and by drying. The syrup can also be fermented to produce an alcoholic drink. Fruits of "Stenocereus" species have also been important food sources in similar parts of North America; "Stenocereus queretaroensis" is cultivated for its fruit. In more tropical southern areas, the climber "Hylocereus undatus" provides "pitahaya orejona", now widely grown in Asia under the name dragon fruit. Other cacti providing edible fruit include species of "Echinocereus", "Ferocactus", "Mammillaria", "Myrtillocactus", "Pachycereus", "Peniocereus" and "Selenicereus".
