Last night I was reading an article that mentioned that three staple crops of the ancient Hohokam culture (the people of the southwest that lived in communities such as Casa Grande) were corn, mesquite, and pitaya. I hadn't heard of pitaya, so I looked it up, it is the fruit of the cactus Hylocereus undatus, known in English as Dragon Fruit. (Pitaya is used to describe the fruit of certain other cacti, that of the Organ Pipe Cactus is called Pitahaya Dulce.) I've had various cactus fruits but seen or heard of pitaya, even though I fancy myself an expert in exotic fruits and there are few I haven't heard of.

Today, following an unrelated link, I stumbled into a recent comic strip that featured the pitaya.
