Bake the sweet potato for approximately 45 min at 375 degrees. Remove from the oven and let cool.
Combine sweet potato, sugar, milk and stir to make a paste. Mix in 2 cups of flour, salt, yeast and spices until throughly combined. Add more flour a quarter cup at a time. Mix in after each addition until you have dough that is tacky but which you can handle with wet hands. When you get to the proper consistency, remove from the bowl and knead by hand for 5-10 minutes.
Set the dough aside and let rise in a covered bowl for 45 minutes to an hour. Divide into a dozen shaped rolls. Then allow to rise again until doubles in size. another hour or so.
Bake at 375 for approximately 20 minutes or until the are lightly browned.
Very yummy as a turkey sandwich.
