Preheat the oven
to 220'C/425"F/Gas 7. Sift the dry ingredients into
a bowl. Stir in the sage and add enough buttermilk
to make a soft dough.
Shape the dough
into a round loaf and place on a lightly greased
baking sheet.
Cut a deep cross
in the top. Bake in the oven for about 40 minutes,
or until the loaf is well risen and sounds hollow
when tapped on the base. Leave to cool on a wire rack.
