How can I be sure to find a potato that will be dry and fluffy when cooked, rather than gluey or wet?

First, be sure to look for the “Grown in Idaho” seal on the potato bags to make sure the potatoes are from Idaho. We grow a lot of potatoes, but only one third of the total crop. Look for the Russet Burbank variety of potato as this potato typically has high solids and bakes up dry and fluffy. The Russet Norkotah variety is currently a favorite of retail produce buyers as it always has a nice, even-colored skin and oval shape. The Norkotah bakes up a little moister than the Burbank.
