Bananas are a mono-crop. There was a disease in the latter half of the 20th century that threatened all bananas on the planet. A particular strain survived. This strain is what you NOW think of as a banana. The candy tastes the way bananas used to taste.

Can confirm. I went on a banana adventure during the pandemic where I ate nearly 10kg of bananas. I learned the Cavendish is a shit banana and we’ve been cheated out of superior nanners for decades.
