Bunny Guinness, Garden Writer and Broadcaster, speaks from experience in the Sunday Telegraph. She has eaten the spuds she talks about and gets opinions from other people who know and care about the taste of the potatoes they grow. Bunny's recent taste tests included several Sarpo varieties and I am delighted to say that both she and her correspondents were very pleased with their flavour.
