potato sourdough starter
I started a sourdough starter yesterday. The recipe is from an old farm cookbook which uses boiled mashed potatoes in the mix, but is a little vague when it comes to instructions. It said to cover so I inverted a glass cake pan over the crock. Within 2 hours it had overflowed the crock. After I cleaned up the mess on the counter, I replaced the cover with plastic wrap and watched it closely. After a couple of hours it went down a couple of inches and this morning it had gone back down to almost the original volume. My question is...did I kill it somehow? Also the recipe does not say to feed it. It say's it's ready to use in 48 hours (storing the remaining starter in jars in the refrigerater). Although I am an experienced bread maker, this is my first attempt at sourdough. I appreciate any comments!
