How often do you encounter bananas that taste similar to banana flavored candies and popsicles?

It's rare. I buy a bunch. Eat two and the rest I bury in the garden around the frangipani.

With bananas there's a fine line between sweet and rotten.

There once was a banana so fair,
Sweet today, but tomorrow—beware.
One freckle too much,
And the magic won’t touch,
It’s perfume by noon, rot by air. 🍌

Ripeness plays a big part.
And theres one type banana thats way better, for some reason

Not often the phenotype of banana that banana candy is based on is very rare these days.
