Place all ingredients in a large saucepan and bring to a boil. Once boiling, lower heat to a simmer and cover. Let mixture cook for about 20 minutes, until pears are cooked through and very tender.
Remove from heat and mash pears with a potato masher or fork. If you want a completely smooth sauce, you can put it in a blender and puree.
Transfer pear sauce to a bowl and refrigerate until cool. Sauce will thicken a bit as it chills.
Serve as a side to a pork or sausage dish or as dessert, a snack, or breakfast. I like to serve with a little ground ginger sprinkled over the top.
