First wash the peaches making sure to use good quality un-bruised peaches. Place the fruit in a boiling pan of water for approximately one minute. Pull out the peaches and place immediately in a bowl of cold, icy water. I did about 4 . -5 peaches at a time and did them assembly style. Boiling water, icy water, then I used my cutting board and cut them in half. Peeled (the skin should come off easy, otherwise you should boil a little bit longer) and pitted. Then place peeled, pitted and quartered peaches in a 6.5 quart slow cooker.
