I went to my favorite Thai market this week and saw something I had never seen before. It looked like a strawberry that had grown up near Chernobyl. In English it's called Rambutan; in Thai it's nga. The fruit is native to southeast Asia, and Thailand is one of the largest growers of it. The skin peels off pretty easily, and the fruit inside is the same consistency of a grape or perhaps a plum. You eat the meat, but not the seed inside. It's not extremely sweet, but it still tastes good. I got a kilo for a dollar.
