ANZAC Biscuits! The acronym ANZAC stands for Australian and New Zealand Army Corps, whose soldiers were known as Anzacs. Anzac Day remains one of the most important national occasions of both Australia and New Zealand. These traditional biscuits were baked by anxious wives and mothers during World War I, packed in food parcels, and sent to the Australian soldiers in the trenches. The biscuits are known for their excellent keeping properties.
