I put the crockpot on low for 8 to 10 hrs. Stirring occasionally. About, 1/2 way through cooking I add my brown sugar....just about 1/2 cup. Then, when they are cooked down where they are nice and soft I remove the cinnamon sticks & blend with my emulsion blender till smooth. I taste and then add more brown sugar if necessary & my salt at this point.
