Preheat the oven to 325℉.
In one mixing bowl, mix together the sourdough starter and honey/maple syrup.
In the other mixing bowl, combine the oats, nuts, seeds, dried fruit, and cinnamon. Then combine the dry and wet ingredients into one bowl and mix well.
Optional: cover the bowl with a towel and let it ferment for 2-5 hours.
Spread this mixture thinly and evenly onto baking sheets lined with parchment paper.
Bake the granola for 20 minutes.
Remove the granola from the oven and let it cool. It will harden more as it cools.
Break the granola into chunks and enjoy as is, with yogurt, or raw milk.
