As mentioned earlier the potato undergoes a structural change when it is heated up. The amylose bound up in a crystalline structure is released during heating. Because the amylose reacts with iodine an easy way of monitoring this reaction is by treating a cross section of the potato with a diluted iodine solution. Distinctive rings spread further and further in towards the center of the potato during baking.
