Chilli Pepper Beef Wellington. British beef fillet is seared, then hand-rolled in portobello mushroom duxelles, folded with silky-smooth Chicken Liver Paté and a generous helping of Fresh Herbs and Proscuitto . It’s then encased in a Spinach and Herb crêpe and wrapped in all-butter Puff Pastry and served with a rich beef and red wine gravy.
