The duration required to cook sweet potatoes via steaming is a function of several factors, primarily the size of the potato pieces and the desired level of tenderness. Smaller, cubed pieces will cook considerably faster than whole potatoes. Achieving a fork-tender consistency is the standard benchmark for doneness.
Steaming offers a method of cooking that preserves nutrients more effectively than boiling. This is because the sweet potatoes are not directly immersed in water, minimizing the leaching of water-soluble vitamins. Furthermore, steaming provides a relatively gentle cooking process, helping to maintain the structural integrity and natural sweetness of the vegetable.
