It's a potato I tried growing in a pot this year. It's a "first early" which I though meant the same as a "new" potato. So I boiled them and they fell apart! Then I looked them up properly and found that they're best for baking - indeed, Waitrose sell them as "summer bakers". According to Alan Romans, William Sim of Fyvie, Aberdeenshire, bred the original "Duke of York". Then in a field somewhere in Holland, it spontaneously mutated into the red form....
