Southern Yams With Marshmallows. Spread the marshmallows evenly over the yams. Combine the mashed sweet potatoes, eggs, butter, vanilla, brown sugar or sweetener, cinnamon, nutmeg, and salt in a mixing bowl.
Drain potatoes and peel once they are cool enough to handle. (i like to use this vegetable scrubber here.) peel and cut the sweet potatoes into thick round wedges. 10 ounces marshmallows directions preheat oven to 400 degrees fahrenheit.
