@ Worldcook - an idea for making pear preserves that have some body. Instead of processing your pears like an applesauce, try this. Peel and core pears. On your food processor, insert a "fine grate" disc. Send your pears down the feed tube and let the processor create a fine shred pear. Toss the shredded pears in a nonreactive pot with a 1/4 cup lemon juice for every 8 cups pears. The lemon not only helps the pH value, but heigthens the pear flavor. Sweeten as you will.
Just an idea. It can help give the preserve a bit more body while keeping the sugar low. Also, adding a little cinnamon can fool the palate into believing it is tasting something quite sweet. I think pears and cinnamon are divine, but then again I put cinnamon in my chili, my spag sauce, my hot chocolate - I'd put it in a pot roast if I remembered to!! lol!
Best of luck!
