What is a waxy potato?
Waxy white and red potatoes have less starch and more moisture than russets and other high-starch potatoes. This low moisture content makes them ideal for boiling, mashing, roasting or frying. New potatoes have a waxy texture and thin skins, meaning they keep their shape in potato salads and can be pan roasted.
Store potatoes in a cool, dark place. Putting them in the refrigerator will turn their starch to unwanted sugar, making them grow unpleasantly dark when cooked.
