Peel and chop the peaches. Place them in a large, heavy bottomed pot. Add the sugar, salt and whiskey. Finely dice the peppers and add them to the pot. Bring to a boil and stir frequently for 20-30 minutes until the jam is thick. Using a hand held blender, blend the peach mixture to the consistency you like. Pour into cleaned and hot mason jars and seal. Serve over your favorite cheese with crackers.
