Roast duck legs with red wine sauce
It's almost impossible to overcook duck legs - so try this rich, slow-roasted dish
Heat oven to 190C/fan 170C/gas 5. Peel, quarter and very thinly slice the celeriac - this is best done with the slicing blade of a food processor. Toss in the walnut oil, salt and pepper, and spread over a gratin dish. Pour over the stock and bake for 40-45 mins, then sprinkle with the walnuts, crumble over the cheese, then cook for 15 mins until crisp and golden.
