Lots of people helped write this book, some of them unknowingly. So, to all the people who have attended my Christmas food talks, and helped me hone the interesting bits, thank you. The same goes for the people who responded so enthusiastically to my mad twitter surveys (or, you know, sent me books or extracts of books or generally wonderful things).
I wrote this during the here-there-and-everywhere-as-long-asyou-stay-home coronavirus crisis of winter 2020–21. Thank you hugely to the University of York, where I am a research associate, for enabling me to access corners of the internet I would not otherwise have access to. Special mention to Chris Johnson of IT Support, who talked me down from the ceiling when I was about to burn my computer due to Endnote issues. And thank you to the team at DeliaOnline for answering my query on editions.
