I made soda bread.

 170g plain flour
 170g self raising flour
 1tsp salt
 1tsp bicarbonate of soda
 290ml buttermilk

 preheat the oven to 200 oC

mix the dry ingredients,
make a well and pour in the buttermilk
mix with a large fork
kneed lightly on a floured surface
place on a floured baking sheet
cut a cross in the top bake for 30mins

lovely, next time i might add a little more salt.
