To cook the sweet potato in an Instantpot:
Place the sweet potato(s) on the steamer rack and pour in 1 cup of water. Set the pressure to high for 10-20 minutes, depending on the size (Mine were super skinny and were overly soft after 12 minutes) Release the pressure. Chill until cold, and then peel and chop.
To cook the sweet potato in the oven:
Bake in a 400ºF oven wrapped in foil for 40 minutes to one hour, or until tender. Chill until cold, and then peel and chop.
