No matter how many potatoes I buy, they all seem to taste the same. All potatoes in their category ... baking, boiling, roasting ... just seem the same. The subtlties are lost on me.
A local market had a variety of potatoes from a top notch farm that has been growing 22 varieties of potatoes since 1922. So I bought one of each the six types available that day ... Durango, Kennebunk, Huckleberry, Viking Blue, Chieftan, German Butterball ... boiled them and did a side by side taste test.
Other than color and texture there really wasn't all that much difference in flavor.
The one exception was the Kennebunk which along with texture that would be great for a French fry, was very sweet and had more intense flavor.
I don't know. Potatoes don't seem to be about flavor. This site has hundreds of links about pototoes and flavor is rarely mentioned about each variety.

Why'd they forget how to grow, POTATOS?
