Oh God, I tried to bake my own (normal) bread a couple of times, but in the end, felt it really wasn't worth it, time-wise. Though you're right, with these rising prices, you never know... Still, despite all the toil (seven days?!), yours turned out looking awesome! Hopefully next time, the taste's on par, too.
Thanks! Even making regular bread is really time consuming. The entire process is kind of relaxing to me though. Since I'm home all day I thought it would be time to master sourdough. Some people feed their starter twice that long (14 days) and that might be why mine didn't rise as well as it should've.
