The Oxford Companion to Food is an encyclopedia about food. It was edited by Alan Davidson and published by Oxford University Press in 1999. It was also issued in softcover under the name The Penguin Companion to Food. The second and third editions were edited by Tom Jaine and published by Oxford in 2006 and 2014.
The book, Davidson's magnum opus with "more than a million words, mostly his own", covers the nature and history of foodstuffs worldwide, starting from aardvark and ending with zuppa inglese. It is compiled with especially strong coverage of European and in particular British cookery and contains no recipes. It was an "outgrowth" of the annual Oxford Symposium on Food and Cookery.
