Popular fingerling potatoes are baby long white potatoes. New potatoes can be any of the three types, but usually refer to baby round red potatoes. White potatoes have a high sugar-low starch content. Use for boiling whole, salads, soups, hashed browns or any preparation where the potato must hold its shape. Russet potatoes are also known as Burbank, baker potatoes and often as Idaho potatoes, though Idaho potatoes can be any one of three varieties grown in the state.
Russets have a high starch and low sugar content.
The potatoes are best for baking and French fries. The dark-orange skin sweet potato has a more moist texture when cooked. Generally, either can be substituted for white potatoes in recipes. Store potatoes in a cool, dry, dark place, ideally at 55 to 60 degrees. Do not refrigerate.
