When we were in China, I had this wonderful fruit that I could not identify. It was white with little black seeds in it. It reminded me most of a kiwi.
When we got home, I did some research, and found out it was called a dragon fruit. Dragon fruit only grow in tropical climes, and they have a very short growing season. So if you see them in your market, not only are you lucky, you will need to pay a pretty penny to get one. They cost 10USD/lb where I live, and they can way over 1/2 pound a piece, so two will probably run you about 15USD.
I found them last week at my local Wegman's. There were only *4* in the basket, so I snagged two. A man was standing next to me, and started following me around. He finally got the courage to ask me what they were (there was no label.) I explained, and told him that I wouldn't buy them unless he knew he'd like it because of the price.
I enjoy cutting them in half, and then scooping out the flesh with a spoon, but when I gave some to my kids, I cut the fruit out like you would a melon.
Here's a picture of the ones I bought. As you can see, this flesh is pink (they call it red, but it's really fuscia). The ones I had in China were white, but they also come in kind of a tangerine color.
