You won't get too many of these to the pound. In fact rather less than one. Granted this is not a particularly attractive specimen but it weighed in at a stonking eighteen ounces and its shape won't detract from its eating qualities.
I can't remember the variety of this potato. I grew it last year and as it appeared to be a fairly good cropper I kept some three dozen seed potatoes to plant this year. As well as producing a good quantity of large tubers the variety seems to have a high resistance to blight. These two factors have convinced me to keep back a few dozen of the smaller potatoes to plant again next spring.
