3 pounds plums (weight with pits removed)
6 cups sugar
1 teaspoon cinnamon
1/4 teaspoon nutmeg
1/4 teaspoon allspice
1/4 teaspoon cloves

Put washed, chopped, pitted plums in food processor or blender and puree.
Pour plum puree into large stockpot. Stir in sugar and spices, then bring to boil over high heat, stirring constantly. Boil for 5 minutes, continuing to stir constantly to avoid burning the jam.
