I just discovered that you can take that first liquid that you get when making the starch (before the rinsing of the starch step) and boil it down to a syrup. You can do this with many of the alternative flour liquids. I will give it a try next time I make the sweet potato starch and flour and let you know what it tastes like. If it tastes great that would mean that there will be almost no waste of the sweet potato. :0)
