Kia Ora,
The NZ in aNZac stands for New Zealand, so although Australians claim these as their own treasures, they belong, rightly, to us both ;-)
Here is the recipe from the "Bible" of Baking, here in NZ - the Edmonds Cook Book(first printing in 1955; the best-selling NZ book ever):
ANZAC Biscuits
125g (4 oz) flour 150g (6 oz) sugar 1 cup coconut 1 cup rolled oats 50g (2 oz) butter 1 tablespoon golden syrup 1/2 teaspoon bicarb soda 2 tablespoons boiling waterMix together flour, sugar, coconut, and rolled oats. Melt butter and golden syrup. Dissolve Bicarb soda in the boiling water and add to the butter and golden syrup. Make a well in the centre of flour, stir in the liquid. Place in spoonfuls on cold greased trays. Bake 15-20 minutes at 180 degrees Celsius/ 350 degrees Fahrenheit.
Enjoy!
