Rustic sourdough bread

It was late at night when I walked into the kitchen, and the bread machine had just finished the baking cycle. The kitchen was filled with the wonderful aroma of fresh baked bread. Pause. ..... Fresh bread. I fell for the seduction and angled the piping-hot loaf out of the machine. What's better than the first slice of fresh, crusty sourdough bread with some butter, even if it is late at night ? 

Sourdough bread:

1/3 cup fresh sourdough
1/2 cup warm water
1 teaspoon salt
1 2/3 cups King Arthur unbleached all purpose flour
1 ts instant yeast (for bread machine)
1/2 TB baker’s milk powder
1/2 TB sugar

Place all ingredients in bread machine, in the order listed, and turn on the machine, and used the setting of firm loaf with normal crust.
