Sweet Potato Biscuits
To make the mashed sweet potato, wrap sweet potatoes in aluminum foil and roast in a 425°F oven for 1 1/2 hours. Turn off the oven and allow the sweet potatoes to cool in the oven for 2 hours. This allows more of the starches in the sweet potato to transform into complex sugars, making the sweet potato flesh both sweeter and softer. Peel and mash the sweet potatoes.
