If you don't have buttermilk on hand, substitute sour milk in the same amount. For each cup of sour milk needed, place 1 tablespoon lemon juice or vinegar in a glass measuring cup. Add enough milk to make 1 cup total liquid; stir let the mixture stand for 5 minutes before using it in a recipe.
Up to 1 month ahead, prepare and bake bread as directed; cool completely but do not drizzle with icing. Place loaves in a freezer container or bag and freeze. To serve, thaw at room temperature for 2 hours. Drizzle with icing.
