Sourdough Sandwich Bread

Ingredients: (for 1 loaf)

2/3 cup sourdough starter fed or unfed

2/3 to 3/4 cup lukewarm water

1 tablespoon olive oi

1 1/4 teaspoons salt

2 1/4 cups flour

1/3 cup steel-cut oats, traditional or quick

2 teaspoons yeast

OPTIONAL: 1 cup chopped Granny Smith apple (about 1 small apple)

Directions: 

1. Combine all of the ingredients in a bowl, the bowl of an electric mixer. Mix until a sticky dough has formed. You should be able to pull it away from the bowl.  
2. Place the dough in a lightly greased bowl, cover it, and allow it to rise for about 90 minutes. The dough will become puffy, though it may not double in bulk.  
3. Lightly grease an 8 1/2" x 4 1/2" loaf pan.  
4. Gently deflate the risen dough, and shape it into a log. Place it in the pan, cover it lightly, and allow it to rise until it crests at least 1" over the rim of the pan, 60 to 90 minutes 
5. Towards the end of the rising time, preheat the oven to 350°F.  
6. Bake the bread for 40 to 45 minutes, tenting it with foil after 15 to 20 minutes; it will continue to brown slowly. 
7. Remove the bread from the oven, and after a couple of minutes turn it out of the pan onto a rack to cool.
