Pick berries. Wash berries. Put berries in a large pot. Add water to just cover the berries. Cook over medium heat on campfire (or grill or your kitchen stove). Stir constantly as heat will allow for 10 to 15 minutes.
Add cinnamon and sugar. Bring to a boil you can't stir down. Cook 5 minutes.
Add gelatin. Cook 5 minutes.
Remove from heat and let cool. If it is like a syrup... use it as a syrup. If it is like jam... use it like jam.
