Thai bananas (Thai: กล้วยน้ำว้า (kl̂wy n̂ảŵā) but more commonly known as pisang awak, the Malay name in most countries) are eaten both raw and sour as well as sweet and yellow all over SE Asia, including here in southern China.
I have often made successful banana bread with them when fully ripe to the point of over ripe.
By the way Thai banana flowers are a delicious and commonly used vegetable here and in Vietnam. Also, grilled sticky rice Thai banana cakes are a common street food in parts of Vietnam.
