Jay Rayner and his panel of food fanatics are in Lewisham, south east London for this week’s episode.

Joining Jay are food writers Tim Anderson, Melek Erdal and Melissa Thompson, and materials expert Dr Zoe Laughlin. In Lewisham’s Prendergast School, the panel discusses a variety of culinary conundrums, from cooking with coffee to the many uses of banana leaves. The panellists also ponder their desert island dish of choice, and their tips and tricks for cooking for one.

Jay chats to Sri Lankan chef and founder of Little Sambol supper club, Gabriella Suresh, about the ins and outs of Sri Lankan lamprais. He also invites Vietnamese food writer, Uyen Luu, to talk about the surprising link between Vietnamese coffee and cats.
