My Granny's recipe for pickled peaches (really good with ham or pork chops or a beautiful garnish for the Christmas turkey). She made them with these little wild peaches that grew on the farm in Oklahoma that they called "Indian" peaches. She did not always peel the peaches, sometimes she left the peel on.
Pickled Peaches
Plunge 6 lbs peaches into a kettle of boiling water for 1 minute, drain & peel, and insert 2 cloves in each peach. In an enamel kettle combine 6 cups sugar, 2 cups cider vinegar and 3 cinnamon sticks. Bring the liquid to a boil over moderate heat stirring constantly. Add the peaches, turn the heat down and simmer for 5 minutes or until peaches are just tender then transfer them with a slotted spoon to 3 sterilized 1 quart Mason jars, packing them tight. Put 1 cinnamon stick in each jar, pour the hot syrup over the peaches. Leave 1/2 inch head space, wipe rims, adjust lids. Process in a boiling water bath for 20 minutes. Makes 3 quarts.
Lacking canning equipment, you could just store the jars in the frig.
