To make the sauce, add butter to sauté pan and place over medium-high heat. At the same time, drop ravioli into the boiling water. When butter begins to turn light brown, add fresh sage. Stir for a few seconds; then add cranberries, and sauté until skins begin to burst. Add molasses, balsamic vinegar, and broth, scraping bottom of the pan to pick up all the flavor of the turkey. Simmer until cranberries are soft and the sauce coats the back of a spoon, about 12-15 minutes. Season to taste with salt and pepper. Be sure to taste sauce for seasoning before you pour it over the turkey!
