Jimmy tours a factory to discover how they manage to make perfect chocolate mini rolls every time. He sees how technology is used to ensure that every batch of batter to make the sponges is the correct consistency, to measure the width and depth of each sponge and to add air to the batter. The baked sponges are formed into rolls on the factory line and then chopped into mini rolls using a vibrating knife to ensure little pressure is used and the air is not removed from the sponges keeping the shape.
