Sourdough Starter Rising

Just a bit of fun today. This is what Sourdough Starter looks like while it's rising. There are many factors that go into cultivating a good sourdough starter, time, temperature, food, water...

As Mike Avery shows on his http://www.sourdoughhome.com/ blog:
Time & Temperature are interdependent.



When I made the time-lapse video above my kitchen was approximately 75 degrees Fahrenheit (next time I'll display a thermometer). You can tell about 4.5 hours in (about 10am) the doubling had completed (the green rubber band is where it started).

I have such a long rise time (12-13 hours) because I can't come home from work in the middle of the day to refresh & feed the starter. So I compensate for the fast doubling time by increasing the ratio of flour & water to starter when feeding.

Most starter feed schedules call for doubling, I actually quadruple to keep the starter at it's fully doubled position for the 12-13 hours I use in my schedule. You can tell at the very end of the video that if I let it go for much longer (4 more hours) it would go 'flat' and eventually return to it's original level.

Go ahead, give it a try - it's not as hard as you think it is, my simple-to-follow instructions and schedule are in this post: http://matts-bread-log.blogspot.com/2008/08/weekly-sourdough-starter-schedule.html
