Pour the blueberry soup/juice and agar powder into your camping pot. Light the stove and bring the liquid to a boil. Reduce to a simmer and cook for 2 minutes to allow the agar powder to mix fully.
Turn off the heat and add the fresh/frozen blueberries. Pour the mix into your Light My Fire SnapBox O BIO. Leave to cool (takes 10-20 minutes depending on outside temperature) Decorate with more wild berries and dried wildflowers. Serve.
