  • SHETLAND BLACK

    Second Early

    The Shetland Black potatoes have a very distinctive deep purple colour and are kidney shaped. The tubers are smaller than most modern potato varieties and their shape can be slightly erratic. When open the tubers flesh is creamy and pale with a ring of purple. The purple colouring may be more pronounced in some tubers than others, and the colour does not survive the cooking process, as the colour inside and the colour of the skin turn a more dull grey. Not only do these potatoes look exceptional, they also have an amazing taste. The buttery flavour and light floury texture is the winning combination- and they taste great when cooked in its skin.

    First introduced as far back as the 1500s they are thought to have been salvaged from a Spanish Armada shipwreck, however the actual origins of this variety remain a mystery.

    They are not as high yielding as other varieties but the taste makes up for this!
