Should sweet potatoes be peeled when preparing them? I want to make a sweet potato dish -- maybe candied yams.  Should I peel the sweet potatoes before cooking or are these recipes intending for me to keep the skin on?  None say to peel the potato first.
Candied Yams, I would peel first.
However, for mashes and other similar soft dishes, I find it best to bake them until soft and then remove the peels when cool.
