Assemble everything in your blender and blend well, then taste. If you think it needs to be sweeter, add a little more liquid stevia.
Pour into a greased 1-quart Pyrex casserole. Cover with foil and put it in your slow cooker. Now fill the space around the casserole with water, up to 1 inch from the rim of the casserole. Cover the pot, set to low, and cook for 4 hours.
Turn off the slow cooker, remove the lid, and let the water cool till you can remove the casserole without scalding your fingers. Chill overnight before serving.
