ANZAC day is celebrated in Australia on April 25. On this day in 1915, the ANZACs (Australian and New Zealand Army Corps) landed at Gallipoli, and suffered the worst defeat in Australian military history. The fallen soldiers of all wars are now commemorated on ANZAC day. Another cookbook stated that these cookies were sold to raise money to help returned veterans. In saucepan place butter, treacle, soda, sugar and mix with boiling water. Bring slowly to boil, remove and add dry ingredients. Mix well. Place spoonfuls about 8 cm apart on well greased cookie tray. Bake at 140ºC about 25 min.
