Sometimes you want to buy an avocado, but all they have are hard on touch and you know they are not ready yet; they are rubbery and untasty.
One can buy them and wait couple days, they ripen sooner or later (hopefully before they get spoiled).
Are there any tricks and tips on how to speed up the ripening? Like special storage, some treatment to the avocado etc.
In general, but mostly in my experience, it's a bit like treating a cold, or a flue: It you don't do anything, it will take 7 days, but with medicine it might only take a week.
In general, there are no natural fast-forward methods for fruits to ripen, at least not to the level that makes it interesting: If the actual specimen of the fruit is willing to cooperate, you might get from X days to X - 1 days, maybe X - 2 in very happy circumstances.
You may be able to force the fruit (or vegetable, whatever) to get to the stage where it fits your needs for processing (heat tends to work nice in general for instance, that's why we cook and fry stuff ), but it won't be the same as ripening that fruit. It's not like the fruit realizes what's going on, and starts to make up for lost time.
