Slice ripe pears (not cored or peeled) into a large saucepan. Add water, cover, and cook for 30 minutes. Remove from heat, and press the pears through a sieve or food mill. Return pulp to pan.
In a frying pan, heat 1-1/2 cups of the sugar, stirring until it dissolves, caramelizes and becomes brown. Add melted sugar to the pear pulp. Add the remaining sugar, cloves, cinnamon and ginger. Cook uncovered, approximately 40 minutes, stirring frequently until thickened. Stir in lemon juice. Remove from heat, and pour mixture into jars. Process in boiling water bath for 15 minutes. Set aside to cool.
