Sweet Potato Donut: Mashed or Powder?
I have been interested in making donut from sweet potato (ipomoea batatas) as I heard it has great health benefits such as high in fiber, beta-carotene, vitamin, and anti-oxidant. However I can't decide whether to use sweet potato powder or simply mash a fresh one.
Making it from powder might be more hassle-free but I suspect the fiber would be gone already as it was broken down to form powder. Also, I wonder how much of the nutrient lost in the cooking process.
