I got this recipe of my mum this Christmas. She had made it for Christmas Eve and the more I ate of it, the more I liked it. I usually prefer mayonnaise, but in this recipe miracle whip works better. This works best if you make it a day in advance and leave the flavours to develop. Bologna is called 'Feine Schinkenwurst' or 'Feine Fleischwurst' in Germany and you might find it in some supermarkets sold as such. I know in the UK you can get it in a ring in Aldi.
