2 1/3 cups whole wheat flour
2/3 cup white flour
1/2 tsp. salt
3/4 tsp. baking soda
8 oz. buttermilk (and maybe a little more)
2 oz. unsalted butter

Mix all dry ingredients together, rub in the butter. Make into a very wet dough with buttermilk or well soured milk. Knead lightly. Put in a greased 7-inch cake tin. Make a cross on top with a floured knife. Cover with a lid and bake in a 375-400°F oven for about 30-45 minutes. Dark, crumbly and delicious.

(You can sour milk by adding 2 Tbl of lemon juice to a cup of milk. Let sit for 2 minutes.)
