Anzac biscuits are associated with which First World War army corps?

Anzac biscuits are associated with the Australian and New Zealand Army Corps, better known as ANZAC.

The corps was formed in Egypt in December 1914 for the First World War and fought during the Gallipoli campaign. It mainly comprised troops from the First Australian Imperial Force and the 1st New Zealand Expeditionary Force, although British and Indian units were also attached at various points.

The biscuits became linked with ANZAC because Australian and New Zealand wives and women's groups are thought to have sent durable oat biscuits to troops overseas. Their ingredients kept well during long naval transport. The biscuit is not the same as hardtack, which was known as an ANZAC wafer and served as a military ration.

The exact origin of the modern recipe is disputed: early recipes appeared in both Australia and New Zealand, and some differed substantially from today's oat-and-golden-syrup version. ANZAC is also the source of Anzac Day, commemorating the Gallipoli landing and later military service.
