I've been experimenting with beer sourdough in preparation for St. Patrick's day. Made a batch of Guinness extra stout sourdough yesterday and will try to attach a couple of photos at the end of this message. Essentially I substituted Guinness for water in my sourdough recipe. Initially it was coming out too heavy, but with a new starter that problem disappeared. The next challenge is to get some green color into the loaf.
The plan is to make two batches: one with Guinness, the other with water and food color. After kneading them both I'll roll them flat, lay them together, then roll the two together. The hope is that each piece of bread will have a spiral pattern of the green dough between the darker Guinness dough.
I'm looking for ideas on how to make the loaves have the spiral pattern in the desired direction. I can't picture how I'm going to take the final dough, let it rise, then cut it into four loaves, rise again in pans, and still come out with the spiral in each piece of bread.
