I've seen this Q&A
And this one
and this one
but none of them answers my question which is:
I have an avocado I cut open but it's not ripe yet. Being that it's already cut what if any are my options? For the moment I poured some lemon juice on the exposed parts, put them in a container and put them in the refrigerator but I kind of get the impression they'll never get ripe in there and I should just throw them away. Being already cut it doesn't seem like I can leave them out of the refrigerator in a paper bag.
Is there any way to rescue these already cut but unripe avocados?
