Thanks for all the great input everyone. I think I may have made a newbie error, and somewhat "hijacked/misdirected" the idea of what I was trying to accomplish when I started this thread. If I can expand on what I am trying to get at....Certain commodities such as sugar, salt, flour, ect... are a given in modern life. Of course, one can make thier own flour and with the proper resources refine salt from natural sourse such as sea water ect. Sugar, being near to my heart, is the one that I chose to explore. There are many different types of sugars available for many uses. Keeping in mine the idea of providing for one's own self, sugar as a daily staple, could it be made on a cottage level? I have thought of many ways of finding sugar or substatutes for it but was looking for other ways of doing it ...or is that even possible, let alone practical. Maple sugaring would be great if I lived in an area with hardwood trees, but alas pine sap tastes bitter. Since I live near the 45th parralle, sugar cane is kind of out of the question. Sugar beets can grow in this area, however, it would be impractical to do because of the scale needed to refine the sugar. Sorghum can be grown this far north, but what would it take to make it into a usable "sugar"? Are there other natural sources to refine sugar? Ignorance brought me to ask about Stevia. All of this is, is food for thought. It comes down to the old adage, "you ain't gonna learn nothing if you don't ask."
Thanks again for all the ideas. I am looking forward to hearing more as well.
