If I had to guess, I'd go with paper for the reason you mentioned...I'd be afraid plastic would cause it to mold....

Personally, I "ripen" mangoes on the counter. If you wish to TRY and speed up the ripening process, try in a paper bag with apple or possible banana. I am not so sure this will give you the best result, taste and quality-wise though. So long as you are not in a rush, just leave it on the counter and let it do it's thing.

By the way, is this mango you are trying to ripen locally grown or purchased from the grocery store ?

Yeah one of my own mangoes. It needs a few day's more. I was about to put it in a paper bag when I started to think, why not just use a common plastic supermarket bag? That's where it is right now. But maybe no bag is needed. Mangoes don't put out ethylene gas the way bananas do. So you do put bananas in a bag to help them ripen

I've had mangoes that fell off prematurely. I exposed them to the sun and made some of it sweet and edible. Salvaging something at least

I would not use a plastic bag as that may have adverse reactions. Really, bottom line here, if it was "picked" far enough along in its development, there will be no benefit to ripening in a bag versus ripening on the counter.

I do the same thing as bsbullie. I just lay the mangoes on the counter. If I ran out of space, I would have them in a metal tray in the oven. Also, every morning I would turn each mango onto a different side to help them ripe evenly.

I also agree about not using plastic bags. It might actually do more harm than good.
