You are looking down into a one gallon jar of sourdough starter. It's been growing for a couple of weeks now and I'm anxious to try it out. I think it will be ready by the end of the week. I know, what the heck am I going to do with a huge jar of starter, especially when a recipe only takes 1/2 a cup?! I may just have to be one of those people who share/cram starter down all my friends' throats/mailboxes!!!
