Ingredients1 celery head, trimmed 25g butter 1/2 onion, thinly sliced 2 bay leaves 100g breadcrumbs 50g walnuts, roughly chopped 40ml white wine 100ml vegetable or chicken stock 100ml double cream 30g grated Parmesan or Gruyere
Method 1. Cut any thick celery stalks in half, trim all of it into thumb-size lengths, then wash and leave wet. Melt half the butter in a large frying pan, then add the celery, onion and bay leaves. Season, cover, then cook over a medium heat for about 30 mins, stirring occasionally to stop the onions catching. 2. Meanwhile, prepare the breadcrumbs. Melt the remaining butter in a separate pan, then toss in the crumbs and walnuts, stirring often until lightly golden and toasted. Set aside. 3. Heat grill to medium. When the celery is tender, turn the heat right up, pour in the wine and stock, then reduce by two-thirds. Pour in the cream, then reduce for a final few mins until you have a syrupy sauce. Check seasoning, tip into an ovenproof dish, then scatter with the breadcrumbs and Parmesan. Grill for 2-3 mins, until the sauce bubbles. Let it sit for 5 mins before serving.
