Pitaya is similar to tunas, but a little smaller and you don´t have to deal with tuna´s huge seeds, pitaya´s seeds are like dragonfruit´s seeds (pitahaya). It is very watery, fist-sized, and drips juice as deep and staining as wine - but only slightly sweet.
An important point to note: Pitaya is different from Pitahaya – a columnar cactus with similarlooking fruits native to northern Mexico. Over the last 200 years, writers in the U.S. and Europe have confused the two names to the point of absurdity. In central Mexico, youwill find the two fruits being sold in different bins, with the less desirable Pitahaya at a cheaper price. In the U.S., you will find Pitaya sold under both names!
