Preheat oven to 180°C/350°F/Gas 4
Cut the Piccolo in half lengthways. Lightly butter a gratin dish.
Put the Piccolo, cream and garlic in a saucepan and bring gently to the boil, season the cream well and simmer for 3 minutes. Layer the parsnips with the sage leaves and hazelnuts, season each layer. Pour over the cream. Cover with a buttered foil and bake 45-50 in the oven or until just cooked through. Place back in the oven for a further 10 minutes to brown slightly. Rest for 15 minutes before serving. Garnish with a few fried sage leaves. This is delicious as a main course served with a spinach salad and bread.
