I went through a similar 'phase' a few years back (I call it a 'phase' because the practice lasted only two years). I made my own soy milk from fresh soy beans, fermented and roasted my own cocoa beans to turn to chocolate, and made century eggs by harvesting eggs from our ducks, covering them in clay and soaking them in a soda ash mix for a month. It was fun while it lasted but things changed and I no longer live on our farm. My current residence has very little gardening space and no grass to raise ducks, rabbits, or Guinea pigs like I used to.
