2 c. whole oats
2 c. buttermilk
1 t. baking soda
2-1/2 c. wholemeal (or whole wheat pastry) flour
salt

Soak 2 c. whole oats in 2 c. buttermilk overnight. The next morning, mix 1 t. salt and 1 t. baking soda with 2-1/2 c, wholemeal flour. Shape into a round loaf in the middle of a non-sticking baking sheet (coat lightly with butter if necessary) and cut a cross in the bread right through it, keeping the shape intact. Bake at 350° for 50 minutes. Cut into slices and slather with butter.
