Peel and chop the Sweet potato. (There are lots of ways to do this. Sometimes it's faster to boil the thing whole and then the peel just comes right off. Or, I just chop it in giant 'circles' and cut the peel off with a knife. That's the easiest for me.)
Put all the chunks in a sauce pan, cover with water, pour in the spices, bring to a boil, and boil until desired softness (about 15 minutes).
Serve! There's no need for extra sugar. If you REALLY want to, you can put a little butter on it, but it doesn't really need it. If you have a severe attack of the sweet tooth, you can add a pinch of stevia to the boiling water.
