3 c  Flour, whole wheat
1 c  Flour, all purpose
1 tb Salt
1 ts Baking soda
3/4 ts Baking powder
1 1/2 c  Buttermilk, yogurt, or milk
-soured with lemon juice

Combine the dry ingredients and mix thouroughly to distribute the soda and
baking powder, then add enough buttermilk to make a soft dough but firm
enough to hold its shape. Knead on a lightly floured board for 2 or 3
minutes, until quite smooth and velvety. Form into a round loaf and place
in a well buttered 8 inch cake pan or on a well buttered cookie sheet. Cut
a cross on the top of the loaf with a very sharp floured knife. Bake in a
preheated 375F oven for 35-40 minutes, or until the loaf is nicely browned
and sounds hollow when rapped with the knuckles. (The cross will have
spread open which is characteristic of soda bread.) From _Beard on Bread_.
