A few weeks ago, I made my first sourdough starter. After days of draining, feeding, and stirring, this weekend it finally produced a batch of amazing breads. In fact, I went a little nuts on one batch, and used almost all of my 'fed' starter, leaving about an ounce left. I figured that it wouldn't be a big deal, and just fed it a much smaller amount of flour and water than I originally would have, thinking I could just let it re-double and re-double over the course of a few days. However, after a few days of this plan, it seems like the starter has lost its doubling power. I've been keeping it in a clear plastic container, so I can see it bubbling, but it never seems to rise or go anywhere. Can anyone tell me if I've killed it, or if it just needs a few more days to recover?
