Damp paper towel is your best friend here. Wrap your pricked potato in one, then place it on a microwave-safe plate. This traps just enough moisture to create a gentle steam bath, giving you that soft, cloud-like interior we all crave.
Cooking time depends on size: a medium spud takes about 5 to 7 minutes on high. Start with 5, then squeeze it gently with an oven mitt—if it gives a little, you’re golden. If it’s still firm, add another minute. Trust your instincts; you’ve got this.
