In this month’s Smorgasbord, we take a look at Purple Pelisse, an excellent-tasting mid-season fingerling variety that has dark purple skin and flesh and is high in antioxidants. Purple Pelisse tubers are ideal for boiling or baking whole. Purple Pelisse chips retain their bright purple color and resist fading. Chips made from Purple Pelisse in an Oregon taste test surpassed All Blue chips in color, appearance, and flavor and had no brown discoloration, a defect common to other purple varieties.
