sourdough pain de mie
I just got this awesome pan from amazon
And I had a lot of sourdough on my hand so I went ahead and made King Arthur king recipe at thie link
but I didn't use the biga I used my sourdough starter which was fed 24 hours before mixing. I used 15 oz and continued the recipe as it is.
It was awesome flavor and fluffness and right away made a sandwich :D
