Although often mistaken for root vegetables, potatoes are part of the tuber family. Simple potato preparations, like mashed, baked or roasted, pair the best with the pork. Use russet or sweet potatoes for a side dish that is sure to impress. New or fingerling potatoes pair well, and are best prepared steamed or roasted. Roasting allows the potatoes to soak up some of the fat and flavour of the pork during the roasting process. Peel the potatoes, cut into 25mm (1-inch) cubes, season and place in the bottom of the roasting dish, stirring occasionally, until the pork roast is done and the potatoes are tender.
