I wouldn't know about Miyazaki if not because of this post. haha! I've seen red mangoes before, but I just thought they were ordinary mangoes. That one that you have is a little lighter in color compared to those Miyazaki ones I've searched for on the internet. I guess it's just a similar variety, as you said, it's not that sweet. But still, that red mango is amazing! It looks like an apple.

thanks for sharing.
