Sweet potatoes: to cook or not to cook? I would like to dehydrate some sweet potatoes. Here I found a recipe for dehydrating fresh sweet potatoes in low temperatures without cooking them first. But here they say that fresh sweet potatoes contain toxins and should not be eaten without cooking. So what is the truth? Is it safe to eat dehydrated sweet potatoes that were not cooked first?
I would prefer cooking them first. Sun-dried sweet potatoes do exist in some parts of Asia as a snack. They are chewy chunks rather than crispy slices as shown in your link. There are also freeze-dried ones around these days. Anti-nutrition contents are not overwhelming in sweet potatoes to my knowledge. So, uncooked should be fine. I think you will get better texture and avoid browning by cooking them first.
