Most new potatoes are waxy in texture, but none of the main British crop are, so it is necessary to purchase Dutch Bintjes potatoes for such uses as Pommes Macaire.
New potatoes should be purchased for immediate use and not kept in store for longer than forty-eight hours because, being freshly dug, they dry out quickly and will not then scrape easily. Old potatoes must be stored in a cool, dark, dry place in their bags, on wooden slats. If they become warm they begin to sprout, and, if kept in the light, they go green and cannot be used. Potatoes pick up other smells easily, so should be kept away from strong smelling materials and commodities. They bruise easily, even in their bags and should therefore be handled with care.
