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.
