1. Place pears, crystallized ginger, and brown sugar in your crockpot. Turn heat to high and cook for about 2 hours. Reduce heat to low and cook for 8-10 more hours, stirring every now and then. The mixture will thicken as it cooks, and it will keep getting darker the longer you cook it.

2. When it has finished cooking, allow to cool completely before passing through a food mill to remove the skins and what remains of the ginger. You can compost these "remains", or they are quite yummy with yogurt. Pour your pear sauce into your glass jar and store in the refrigerator to enjoy over the next few weeks. It's delicious on toast, in yogurt, and anywhere else you'd use a fruit sauce or butter.
