Found this great BBC documentary with the late Clarissa Dickson-Wright who had a TV show entitled The Two Fat Ladies with her partner Jennifer Patterson.
It is all about food and why we eat what we do today. How food travels through social classes and time, influenced by fashion, money and religion. This being Thanksgiving Season just loved watching it. Some of the recipes presented I tried and loved. Fortnum and Mason so wonderful to shop in and their restaurant is first class.
