Wash the potato well, then wrap it up in plastic wrap. Wrap it loosely.
Cook in the microwave for about 3 1/2 minutes. It will be hot, so let it sit in the microwave for about 5 minutes. The skin will become shriveled, but that's okay.
Once you can hold it, remove the skin through the plastic wrap, a paper towel, or a dish cloth.
When washing the potato, cut off the eyes. If cooking a large potato, rotate it mid-way through cooking.
Story Behind this Recipe
I wanted to make some potato salad for lunch, so I thought I could make a small amount in a short time using the microwave. Our microwave has a setting for root vegetables, but I played around with it to find out what works best for those without such a setting. I tried out various things, but the amount of time it takes varies.
At first, I wrote that it takes about 5 minutes for a 200 g potato, but it ended up a little tough, so I changed it to 3 1/2 minutes for 100 g.
