From Not Your Mother's Slow Cooker Cookbook
6 apples, peeled, cored, and quartered
6 firm pears, peeled, cored, and quartered
1/4 cup sugar or honey (optional)
1/2 cup water
2 tablespoons fresh lemon juice
1 chunk fresh ginger, about 3 inches long, peeled and minced
3 tablespoons unsalted butter
1. Combine all ingredients but butter in the slow cooker. Cover and cook until the fruit is extremely tender and falling apart, on high for 3 to 3 1/2 hours or low for 5 to 6 hours.
2. Beat to make a coarse mash or use a handheld immersion blender for a smoother sauce. Stir in the butter. Serve immediately or refrigerate and serve cold. The fruit sauce will keep, tightly covered, for up to 2 weeks in the refrigerator.
