We always cook our baked potatoes in the microwave. John loves them so I find myself cooking them all the time! I found this helpful hint and wanted to pass it along.
After you clean the potato poke several holes in the potato with a fork then make legs for the potato from toothpicks. This helps cook it evenly without any dry or hard spots.Then wrap a warm moist paper towel around and under the potato and cook 7-10 minutes depending the size.
