Mark is lucky enough to spend most of his time eating, growing, writing and talking about food. His A Year at Otter Farm and A Taste of the Unexpected both won Food Book of the Year, for Andre Simon and the Guild of Food Writers, respectively. His book Sour was Food Book of the Year 2019 in The Sunday Times and Daily Mail.
