Any variety of potato that is harvested early is considered a new potato. Since they are picked before their sugars have converted to starch, new potatoes are crisp and waxy and high in moisture. They also have thin skins, making them great for cooking and eating unpeeled.
In Season: New potatoes are in season in spring and early summer.
What to Look For: New potatoes should be firm, smooth, and free of cracks or soft brown spots. Choose potatoes of similar size so they cook evenly.
How to Store: Potatoes should not be refrigerated; keep them in a cool, dark place and use within a week or so of buying.
