Travelling to make television programmes means I have some unusual food memories. In Pasto, Colombia, I was taken to a restaurant where I chose my meat for the evening from a cage of white rats. It tasted perfectly good - like rabbit.

Food is about communal togetherness. Our family does sit at the table. I think it's a great tragedy if a family doesn't have a table, as there is such an atmosphere of good will and warmth when we have eight people sitting around it.
