Dr Annie Gray, Tim Anderson, Sophie Wright and Jeremy Pang join virtually from their kitchens to answer culinary questions sent in from the audience via email and social media. This week, the team discusses the best way to make a rosti, whether pomegranates are worth the hassle, and the history of the stock cubes. They also talk about adding a shine to pastry - for which Dr Annie Gray has a very unusual solution.
