1. Heat the oil in a large flameproof casserole or deep sauté pan. Add the pork steaks and brown them for 3–4 minutes on each side. Transfer the pork to a plate and set aside.
2. Add the onion and celery to the oil remaining in the casserole and cook, stirring, over a moderate heat for 2–3 minutes. Add the sweet potato, cover the pan and sweat the vegetables for 3–4 minutes or until softened.
3. Stir in the cranberry juice drink, stock, ginger, marmalade, sherry, five-spice powder, star anise and a little salt and pepper. Bring to the boil, then reduce the heat and return the pork to the casserole. Cover and cook gently for 15 minutes.
4. Add the tomatoes to the casserole, cover and cook gently for a further 5 minutes or until the tomatoes are lightly cooked, but still hold their shape. Taste for seasoning, adding more salt and pepper if necessary, and serve, garnished with spring onions.

Some more ideas

Add 400 g (14 oz) cubed pumpkin or butternut squash instead of the sweet potato, and 1 small bulb of fennel, chopped, instead of the celery sticks. * Tomato rice goes well with this casserole. Bring 200 ml (7 fl oz) water to the boil and add 225 g (8 oz) rinsed basmati rice, 1 can chopped tomatoes, about 400 g, with the juice and 4 chopped sun-dried tomatoes. Cover and cook gently for 10 minutes or until the rice is tender and has absorbed all the water. * For a rich fruit casserole, add 200 g (7 oz) pitted, ready-to-eat prunes and 2 cored and thickly sliced dessert apples instead of the tomatoes. Omit the sherry.
