Susan Campbell (1931-2024) co-founded the Walled Kitchen Garden Network in 2001 with the late Fiona Grant. Susan began researching the history of walled kitchen gardens in 1981. She personally visited and photographed over 600 walled kitchen gardens in the UK and abroad, making her a foremost authority on the subject. When sharing here top 10 cookbooks, she noted: "I could easily list ten cookery books that are my favourites simply to read or to look at – glossy books with incredibly complicated or exotic recipes and beautiful illustrations - but they are not by any means the ones I regularly use as books to cook from. Below is a list of ten of the cookbooks which I use year in, year out; favourite standbys, given in the order of their publication and, because many are paperback editions, showing their age by falling apart."
