Share #1: Purple Viking Potatoes â We will feature a different potato variety for each share, and this one is a new one for us. These Purple Vikings looked fun when I was looking at seed potatoes this spring. They are funky and kinda gnarly, and some of them really have that bright fuschia and purple swirling action. Enjoy the crisp white flesh, and the bright skins. Try baking them whole to keep the bright skins intact.
