Secrets, please. I have -- to date -- been unsuccessful.
Fried:
This is from Blue Mesa Grill, served as a restaurant would serve tortilla chips - and just as delicious.

Have sliced them a bit thicker, 1/4” and fried till dark and crisp on the outside, soft in the center. Sprinkle cinnamon/granulated sugar mixture and dig in.
Baked:

NOTE: when cooking the sugar oozes from the pierced skins (best to line pan with aluminum foil)
Prefer to bake and serve with butter only, leaving the cinnamon/sugar, maple syrup to the other guests.
Sweet Potato Souffle:
BTW - contrary to popular belief, few really appreciate marshmallows on top of sweet potatoes.

Sweet Potato Pie:
Tastes much like Pumpkin Pie

Unlike Whites,Idaho or Russet, it is not recommended you eat sweet potato skins. For mashed sweet potatoes, bake in oven and skin, mash them with butter and seasonings (your preference)and a bit of cream. No gravy needed, have yet to find one that enhances the flavor.
