That is exactly what I am referring to! … Idaho Russets.
When you buy "Idaho" potatoes in the store 99.9 percent of the time buying russets. According to the Idaho Potato Commission [no, really] it is incredibly uncommon to find a non-russet Idaho sold outside of the state.
The potatoes I mention in specific are the "Idaho Russet Burbank" … they are a hybrid that was developed by a guy named Burbank. The Burbank and the Norkota (and really Idaho russets in general) specifically have a lower sugar profile and a higher ratio of solids to moisture, fewer eyes and an oblong shape.
On the other hand, one might want a much different potato such as a Redskin or Yukon Gold for, say, potato salad. It really depends on what you’re usin ’em for.
