I have often read about these baked potato bags...and I just have to wonder....WHY? Why, actually, would one need a bag? I just prick my potatos and stick them in the microwave for the preset amt of time and when they are finished, I just wrap them in a tea towel for a few minutes while putting the rest of the meal on the table. Then I just toss the tea towel in the laundry hamper. Am I not getting something here? And, I am in no way trying to be critical...I just don't understand! Please enlighten me.
