Final answer:
Wrap potatoes in aluminum foil before baking to keep the skin soft and make the inside less fluffy due to steaming.
Step-by-step explanation:
When baking potatoes, to keep the skin soft and make the inside less fluffy as a result of steaming, you should wrap the potatoes in aluminum foil. The foil traps moisture and steams the potatoes, which results in softer skin and a less fluffy interior compared to baking potatoes unwrapped. If you prefer a crispy skin, you would bake the potatoes without wrapping them. Wrapping potatoes in aluminum foil is a common practice and ensures even cooking while also allowing for a soft skin texture that can be easier to eat or remove.
