I harvested the first 'Red Norland' potatoes from my garden recently. I think my days of planting grocery store potatoes is over, because these guys were absolutely perfect. I guess there is an advantage of starting with certified seed potatoes. The grocery store ones weren't that bad, but these are great!
I have only harvested a few so far (I want to let the rest size up a bit), but they were very tasty and creamy.
