I've bought a fresh mango for a recipe, I've not used mango fresh before and it's currently pretty green (there didn't seem to be any that were more ripe at the shop) and came with a sticker on informatively saying just "Ripen at home".
So, what's the best environment to help it ripen?
Should it be refrigerated during ripening and/or when ripe?
And how do I reliably tell when it's 'ready'?
