I am thinking about getting a Sodastream but I am not really interested in using their syrups. I have lots of recipes for citrus syrups and fruit syrups. I have a copy of Open Cola somewhere I wanted to try to turn into a diet soda for the hubby. What I have not been able to find is a Dr. Pepper type recipe to make a syrup out of. There must be one floating around somewhere since many grocery stores have a knock off version. Has anyone ever seen anything similar to a Dr. Pepper type drink syrup?
