I've become fond of little Asian (?) bananas...
Grew some here, about as long as your big finger but fatter, with a very thin skin.
Firm inside even when the outside has gone black, much longer shelf life than what gets sold at the grocery store (Cavendish).
Maybe this:
"
Manzano This variety, native to Central and South America, belongs to a subcategory known as apple bananas, and the name fits. The texture of a Manzano is firmer than that of the Cavendish, and the scent is complex, marked by a strong tart-apple aroma. The taste, too, is tart—at least when you first bite into the fruit, whose flavor quickly gives way to sweetness. Though you can sometimes find Manzanos at supermarkets, Asian specialty stores are your best bet."
