According to Australian War Memorial website, The original Army biscuit or Anzac tile or wafer was a long shelf-life, hard tack biscuit, eaten as a substitute for bread. Unlike bread though, the biscuits where very, very hard. So some soldiers preferred to grind them up and eat them like a porridge. The origins of the current popular oat and coconut biscuit we now call the Anzac biscuit are the subject of much debate between New Zealand and Australia with both countries claiming the first recipe.
Our recipe is a combination of the very early and coconut free version on the Australian War Memorial website and the classic recipe in the Women’s Weekly cook books.
