When World War II began in September 1939, petrol was the first commodity to be controlled. On 8 January 1940, bacon, butter and sugar were rationed. Meat, tea, jam, biscuits, breakfast cereals, cheese, eggs, lard, milk, canned and dried fruit were rationed subsequently, though not all at once. In June 1942, the Combined Food Board was set up by the United Kingdom and the United States to coordinate the world supply of food to the Allies, with special attention to flows from the U.S. and Canada to Britain. Almost all foods apart from vegetables and bread were rationed by August 1942. Strict rationing created a black market. Almost all controlled items were rationed by weight; but meat was rationed by price.
