I’ve been making sweet potato powder for a long time . It’s a dense powder that makes a perfect bag to store. I steam my taters first, then put on trays to cool. My wife wants them straight, without any extras, which can be added later. But we have SO MANY fresh sweet taters that we never look for the FD ones. Oh well, someone in the future will be well fed!!
There are hundreds of sweet potato stews you can make, all yummy, esp. with lots of garlic and onions.

Takes about 34-37 hours to FD (I prefreeze mine). i have been breaking them into small 1” squares and pkg them in mylar bags or mason jars. I’ve rehydrated them and they taste fresh from the garden! I wondered how they would rehydrate if I powdered them… that would take way less space to store!
