M&S salad potatoes are selected from the best varieties for a consistent flavour. Always pick of the crop. Potassium is important for a healthy blood pressure. Vitamin B6 helps the body use protein from food. Vitamin C is important for healthy skin, blood and bones. "These are a regular fixture on my weekly Ocado, and we get through an unbelievable amount of them at home. I certainly need them for making My Favourite Potato Salad (the recipe for which you can find on the Ocado website) but I need them, too, for what have become known as the House Potatoes, when they’re just steamed then tossed in a golden pool of Mellow Yellow Oil (also on my aisle) along with a generous amount of freshly ground pepper and Maldon salt, to be eaten at a warmish-room temperature. Sometimes I halve them lengthwise before steaming, sometimes after, or I just crush them lightly as I add them to the serving bowl. And obviously they are a joy, too, with melted butter instead. But however you decide to dress them, the key is to steam them, not boil them." Nigella Lawson
