Someone summoned me at the mention of sweet potatoes. My Southern heritage takes notice. They're really delicious and if you want to split one fresh out of the oven & put some butter in it, maybe a little bit of brown sugar (cinnamon if you like), and eat it in the jacket--That saves all the mashing of it.
Brown sugar. Butter. Cinnamon. (NO marshmallows.)
I was amazed later to find out how great just plain baked sweet potatoes were.
Baked in the skin, the way people bake 'regular'/'Irish'/plain white potatoes.
Did you boil them or what?
