For me the difference is Yam taste good as flavor for ice cream but I dont think sweet potato will taste good as ice cream. What do you think? I also think that yam is more sweeter than sweet potato and sweet potato is sweeter than plain potato.
I can't imagine either one being a flavor of ice cream. That would not be a good taste to me. Thanks for your input but I truly thought the sweet potato was sweeter. I guess I will have to do a test myself.
nutritionally they are the same, both are good source of complex carbs, the only difference i know is there glycemic index, i'm not quite sure which has higher glycemic index, but sweet potato has ideal glycemic index (55%)..
