I bought a starter and a book, Classic Sourdoughs by Ed Wood and Jean Wood. The starter activated and grew nice and bubbly. I neglected to feed it for about a week and it became too acidic. I kept it refrigerated and expected it to go dormant. I was using two mason jars with coffee filters over the lids to keep my starter in. When I went to use some, I found about a quarter inch of hooch on top of the starter. I stirred the hooch in and used it to make bread dough. I hoped that maybe it would work out OK. I proofed the dough for twelve hours and it failed to rise. It just turned to goo.
I've watched several videos on how to regenerate sourdough starter. The consensus seems to be to start over using a small amount of the starter that went dormant, and to feed it twice a day. There are, however, two schools of thought on what to do with the hooch; stir it in or pour it off. As I have two starter jars, I decided to try both methods. After three days of feeding every twelve hours, both batches of starter are bubbling. The batch that I poured off the hooch does appear to be a bit more active with bigger bubbles. I think that I may be able to bake some bread Sunday.
My reasons for going down this path is to eat healthier. I have restricted by carbohydrate intake. The sourdough is for a once a week treat of biscuits, bread, or pizza.
