Mix the buckwheat, coconut, almonds, cinnamon, and flax together in a mixing bowl.
Blend together the almond butter, water, and coconut syrup. Pour it over the dry ingredients and use your hands to mix it all thoroughly.
Place the granola onto a Teflex-lined dehydrator sheet (you can use parchment paper in place of Teflex) and dehydrate at 115 degrees for four hours. Mix the granola up a bit and break it apart on the sheet. Dehydrate for another four hours, or until totally dry.
Alternately, you can toast the granola at 325 degrees for about twenty-five or thirty minutes, or until it's golden and fragrant. Allow it to cool completely before serving; it will firm up as it cools.
Makes 3-4 cups.
