STEP ONE: Add a large pot on the stove over medium-high heat and bring to a boil. Peel and cube the sweet potatoes into small cubes. Place the sweet potato in the boiling water and cook until fork tender - for about 10-15 minutes. Once tender, remove from the heat, drain in a strainer, add to a bowl, and mash until smooth with a fork. Set aside to cool slightly while you prep the rest.
