Secondly, because you save more money (again?) as you use that fruit nobody eats and you always buy promising yourself you'll take it this time, you'll make juice for the kids, a delicious pie...
Thirdly, because it's a natural product; you'll be sure of eating at least one thing without industrial additives.
Besides, because you decide if you want to eat tons of sugar or sweetener or nor; I didn't do it and, trust me, they're delicious...and with less calories!
Finally, because it doesn't take too much time, especially if you have a kind machine like thermomix, which cooks it by itself. If you don't have it you only have to stir it from time to time.
