Place your potato in your microwave on a plate of some sort. Set the timer to six minutes on high power. Once it's done, flip your potato over and cook it for six more minutes. After it's done cooking, take it out of the microwave. Be careful, it's hot. By the way, most microwaves differ, so you are going to want to check your potato every 3 minutes or so by stabbing it with a knife and checking for resistance. You have PKM
