These small bananas, native to South-East Asia, in Thailand and also Vietnam, are sweet and much smaller than the better liked variety of bananas that you can find in all supermarkets. They are also much more expensive, maybe 4-5 times. They are used to make steamed banana desserts in Thailand. As you can see, I'm in the wait-till-it's-black camp, I don't like them green. In all, despite their price, I think that they taste way better than their bigger brother.
