The recipe for this World War One Trench Cake shows how truly inventive people had become in the name of morale-lifting home-baked treats. It was designed with a specific purpose – to be sent by post to the soldiers fighting in the trenches.
Instead of fats, like butter, they used dried fruits - this helped keep the cake moist for a long time which was perfect for the long journey to the front line. The recipe included very little flour (a rationed item) – this helped to keep it small and dense, ideal for fitting in a parcel to post to the trenches. And finally, you won’t find any eggs in this recipe - they substituted vinegar for this luxury item to help the cake rise.

4. Add the dry ingredients; brown sugar, currants, cocoa powder, nutmeg, ginger and lemon zest, and mix to combine.
5. In a separate bowl, mix together the milk, vinegar and bicarbonate of soda.
6. Add the milk/vinegar/bicarb mix to the dry ingredients and mix well to form a thick batter.
7. Pour the batter into the cake tin and level out the mixture with a palette knife.

8. Bake in the centre of the oven for approximately 1 hour or until a knife inserted into the centre of the cake comes out clean.
9. Allow to cool slightly before removing from the tin and placing on a rack to cool completely.
