Lamb bangers with sweet potato mash

Place the sweet potatoes and floury potatoes in a large saucepan and cover with water. Bring to the boil and simmer, covered, for 15-20 mins, until fully cooked and tender. Drain and return to the pan. Mash the potatoes and stir in the ground cumin and butter until smooth. Season with salt and freshly ground black pepper and keep warm.

Meanwhile, heat the oil in a large frying pan over a medium heat, and cook the sausages for 5 mins on each side. Add the Belazu onions with their balsamic liquor and bring to the boil. Lower the heat and simmer for 5 mins until the sausages are cooked and the sauce reduced. Stir in the redcurrant jelly and season to taste. Serve with the sweet potato mash and some blanched spinach.
