I've got some of this cooking in the oven as I type this

Irish soda bread
Ingredients
170g/6oz self-raising wholemeal flour
170g/6oz plain flour
½ tsp salt
½ tsp bicarbonate of soda
290ml/½ pint buttermilk
Preparation method
1. Preheat the oven to 400F/200C/Gas 6.
2. Tip the flours, salt and bicarbonate of soda into a large mixing bowl
and stir.
3. Make a well in the centre and pour in the buttermilk, mixing quickly
with a large fork to form a soft dough. (Depending upon the
absorbency of the flour, you may need to add a little milk if the dough
seems too stiff but it should not be too wet or sticky.)
4. Turn onto a lightly floured surface and knead briefly.
5. Form into a round and flatten the dough slightly before placing on a
lightly floured baking sheet.
6. Cut a cross on the top and bake for about 30 minutes or until the loaf
sounds hollow when tapped. Cool on a wire rack.
