I remember the hostess made these at the very first dinner party I was invited to. Unfortunately she was a very ordinary cook and to make matters worse, she hadn't ever made these before ie prior to the party. The poor thing was so flustered when the chicken turned out dry as anything ie cooked too long, the cheese had oozed out of everywhere and lord knows what happened to the ham- I think you could probably carbon date it , it was so tough. Needless to say she has never made them since and buys them from her butcher! I love the sound of this recipe, I'll give them a go with gluten free breadcrumbs- cant wait to try them.
