Because potatoes take awhile to cook it is sometimes useful to give them a bit of a head start, and that is where parboiling comes in. Once they have parboiled they have many uses. I put them in salads, fry them up for hash browns or cut them in thin slices and put them on pizza.
Cover the potatoes with room temperature water and bring to a light boil. Boil for 10-15 minutes (about 15 for a large potato). Take potatoes off the heat and immerse in cool water. Let cool before you handle them. This works best with boiling potatoes.
