Turnips and Swedes are closely related and come in an array of shaped and sizes, depending on age and variety. The most common type of turnip in Australia has a purple top with a white globe and white flesh. Turnips are also called neeps in Scotland or rutabaga in the US. Select turnips and Swedes with smooth skin and firm flesh with no blemishes or soft patches. Attached greens (if any) should be bright and fresh. Turnips and Swedes are best kept in the crisper section of the refrigerator. Turnips and Swedes are available all year round but most are harvested from late spring to autumn.
