It tastes like that because it was flavored to taste like the michel gros banana.

It probably doesn’t taste exactly like that either, but that’s why it doesn’t taste like the Cavendish banana that you’re used to.

Wasn’t Hank Green who made a video about that?
Probably dozens of people have. Can’t remember the channel name (it was the name of their candy shop but fuck me if I remember the shop’s name) but I saw a video from a candy maker about that about 10 years ago.
Boy, I haven’t thought of Lofty Pursuits in a long time
