First World War Trench Cake

The official recipe released by the government so the public can bake the traditional cake sent to soldiers in the trenches during the First World War.
During the First World War people in Britain would bake and post a fruit cake to loved ones on the front line. Some traditional cake ingredients were hard to come by.

There are no eggs in this recipe and vinegar was used to react with the baking soda to help the cake rise.
