This is an old time recipe that my mother and grandmothers used to make pear preserves. They used whole cinnamon sticks and cloves, but I've used ground and they taste good too. I experimented with watermelon rinds and found that the basic recipe works just as good. I did cut back on the sugar, originally it calls for 2 parts fruit to 1 part sugar, which is a bit much for my liking. The end result is a syrupy sweet fruit preserve, not like the preserves that are store bought, so don't expect store bough consistency. These are good old time simplicity.
