This month, the Smorgasbord takes a look at AmaRosa, a unique fingerling variety high in antioxidants and with excellent flavor.

AmaRosa is a mid-season specialty potato with red skin and red flesh. It is unique among commercially available potato varieties as it sets a large number of smooth, small, fingerling-shaped tubers with red skin and red flesh and excellent culinary quality.  Tubers are ideal for microwaving, frying or baking.  Chips made from AmaRosa retain their rosy color and resist fading.
