Fill a
6-quart CrockPot or an 8-10 quart stock pot with prepared fruit. I heap the fruit up a little above the pan because it will cook down quite a bit. Pour an inch or two of water or no-sugar-added apple juice in the pot, and cook the fruit.
On the stove top, cook the fruit for a half hour or so on high (or the highest heat you can use for your pot).
In the Crock Pot, cook the fruit on high for about three hours.
