This was first found in a Dutch crop of Duke of York (Eersteling). It has deep red skin colour, it is more vigorous than white Dukes and has spectacular foliage with blue “centres”. With great flavour and large tubers this is one of the few heritage varieties to gain a little modern commercial success – Waitrose summer bakers + Marks & Spencer heritage crisps. The one variety I would have to chose for the proverbial desert island.
