Preheat the oven to 200°C. Prepare a baking tray by covering it with baking paper.

In a large mixing bowl stir together the wholemeal flour, plain flour, soda and salt.

Make a large hole in the middle, pour in the buttermilk and mix thoroughly with the dry ingredients using a fork. You might need to add a bit more buttermilk if the flour is more absorbent and the dough seems too stiff, but it shouldn't become too wet or sticky.

Place the dough ball onto a lightly floured surface and knead.

Form into a flat round and place the dough on the prepared baking tray. Cut a cross on top of the bread.

Before the bread goes into the oven I like to brush some melted butter over it so the crust gets more golden.

Bake the bread for 30 minutes. Let it cool on a wire rack.
