Preheat the oven to 230°C (Do this early because the bread dough is made in a few minutes).
Dust a chopping board with flour and place to one side. Dust a sheet of baking paper with flour and place to one side.
In a large bowl mix all the dry ingredients together. Make a hole in the middle and pour in the butter milk.
Using one hand, gently mix in a circle starting in the middle working to the outside until you have a soft, not too wet and sticky mass. Important: Do not knead or press the dough too hard. Turn the mixture out onto the dusted chopping board.
Now you have to be quick and gentle!
Dust your hands with flour and roll the dough gently into a round shape. Transfer to the dusted sheet of baking paper and press gently until it is between 5 to 7 centimetres thick. Cut a 1cm deep cross in the top of the dough.
Place the baking sheet with the dough in the oven and bake for 15 to 20 minutes. Reduce the heat to 200°C and bake for a further 20 to 25 minutes.
To test if the bread is cooked, remove from the oven and tap the bottom. If it sounds hollow, it is cooked.
