When we traveled through China, our tour guide purchased several dragon fruits, and served them with one of our meals so that we could try them.
This look like this - pink on the outside. The peeling is actually not too thick and peels off quite easily. So I bought one at my local Sprouts because I wanted to see if there was any difference with the ones purchased in the States.
All of the ones I saw in China were white with small black seeds - kind of like a kiwi. You can imagine my surprise when I cut it open and found this - a hot pink dragon fruit.
They looked like the color of beets. The color temporarily stained my hands.
They are good, but truly reminded me more of a sweet beet than a fruit. For the price I had to pay at Sprouts for one ($6!!!), I don't think I will try it again. The price in China? $3.
