Yesterday I tried making sourdough bread again. It took the sponge eight hours to rise. Then two more hours of rising after flour and kneading, then it needed to be shaped and rise for two more hours so I just left it in the bowl overnight. I took it out this morning, turned it out onto the counter, and put my hands into a mess like what you see in a taffy puller. I managed to scrape it off into the trash.
So after that I figured out the secret to making sourdough. Throw the fucking starter in the trash and just make bread with dry yeast. No caring for the starter, no waiting all day for the sponge to rise, and a lot less sticky mess.
