To welcome visitors to the city and get them familiar with the local cuisine, Great British Bake Off star Lizzie Acker has created a modern spin on a retro Liverpudlian dessert. The wet nelly is a bread and pudding type sweet which dates back to the 1950s. Lizzie who is a huge fan of the song contest has teamed up with Oatly to give guests at a local cafe a free slice.
