Garlic, onions, ginger, sherry and a soupçon of cinnamon - the air is redolent with these scents and the underlying base of lamb.  This casserole has been simmmering for ten hours in the slow cooker and I inhale deeply as I enter  my apartment. The scented air envelops me like a warm blanket and I feel the tensions of the day slipping out the door behind me. This is comfort food indeed.
