Here is the crumb from my first sourdough..

Toast

We scarfed down half the first loaf in minutes for lunch today.  I am lucky I got a picture of the inside before it was gone!  This is the best bread I have every made, and I've been baking for more than thirty years.  I already have a request for more for this weekend, so now I have to learn how to take out the starter from the fridge and liven it up...  Back to the forum for advice!
