I've grown kennebeck potatoes for the past 10 years and are my wife and my personal favorite. We like them Mashed, Baked, fried with onions, or cut up, oiled, salted and rolled up in foil and thrown on the grill while cooking out ( makes a great French fry of sorts; a favorite of ours). There is nothing as good as creamed baby potatoes and peas fresh out of the garden. It makes my mouth water just to think of it.
Potatoes are a must in my garden; a great productive crop to grow using a variety of methods depending on your situation. Kennebeck seems to grow good for me here in Iowa.
I have found potatoes a very forgiving crop to grow and I usually have enough left in the spring to just plant the whole potato, which usually gives me excellent results.
