Onion Caraway Bread

I made a delicious onion bread I found in the King Arthur Flour Baking Book.  I don't usually think of onions in a  sweet bread.  But this combination is like comfort food.  

A rich dough with butter, sugar, milk, and sourdough starter.  Then on the second rise, adding chopped onion and caraway sprinkled on top.  Also baked on a bed of cornmeal sprinkles.  This is one of my new favorite breads.
