One variety of sweet potato is pale, dry and mild and the other is deep orange, moist and sweet. For the best flavor and color, use orange-fleshed sweet potatoes.
Depending on size, the red and sweet potatoes may need different cooking times. Check them after 15 minutes. Remove the potatoes that are done, and continue cooking the remaining potatoes.
Prepare the potatoes, cover and refrigerate them for up to one day. Warm the potatoes in the microwave before continuing with the recipe.
