One of my summer hobbies is visiting National Trust properties and other country houses in England and Wales (and Scotland, when I get that far north), mainly for the wonderful gardens that many of them have. In some of these gardens, the NT have maintained part of what was once the kitchen garden, so we can get some idea of what such places may have looked like when they were the main source of fruit and vegetables for the house.
I picked up this book in the shop of a National Trust property somewhere in England. If you want to see what kitchen gardens looked like, this is not the book for you as there are only a few black and white illustrations. The book is a collection of essays, and covers everything from methods of growing different crops, how gardens were laid out at different times, the staff employed, how year-round supplies of food were ensured, and even something on cooking and using herbs for medicine.
