Peaches tend not to be ripe when you buy them. Or at least when I buy them. Thus if you put them in the fridge right away and never take them out, they never do ripen. So when you eat them, they're mainly hard pulp. This can be avoided by putting them by a window for a little while. A couple of hours before sunset, or all night if there's not enough daylight.I include this only as an example of real basic stuff that I've only learned recently.
