They’re not plantains, they’re bananas. We have many varieties here that I’ve never seen in North America – some that are about 4 inches long (finger bananas, a bit rubbery, and very sweet, and frequently eaten smashed into rice and curry), some that are red (also very sweet, considered to be dessert bananas), others that are yellow when ripe, others that are green when ripe. Some are short, like the finger bananas, others that are up to twelve inches long. All sweet and basically what you know of as bananas.
What you call plantain are also available here. But this is also where I mention that, in Sri Lanka, all bananas and plantain are locally called bananas or plantain with no distinction made between the general terms.
And I managed to salvage all of them. None of them busted open on to the floor, just to open air, and what with the thirty second rule and all . . .
