I used this as a rerference. http://infobella.wordpress.com/2009/03/03/banana-ripeness-scale/ To them, once a bannana is brown it is unedible. For me, that is ridiculous. I like most of my bannans at around 75% brownness (?). Sometimes at that level you will get bad bruises but I sometimes find 90% browned bannanas that are perfectly fine. Sorry for shitty layout, I'm on ios.
