I'm doing the same. Not knowing enough about storing yeast long term, I am experimenting with sourdough bread. I think I am going to get sourdough bricks. I've tried twice to create the starter from scratch. I don't think this is working. My wife is greatly entertained by seeing my messing around in the kitchen, however.
LOL! Is this the first time you’ve been cooking much?
I hear ya on the sourdough thing. I did the same thing, since I’m worried about my yeast not lasting. I even bought a sourdough starter after making my own was a disaster. That didn’t work either. The only way I’ve gotten a sourdough loaf that I liked (ie., was light enough to NOT use as a structural material) was to add extra yeast. Thereby, ruining the whole ‘using sourdough as a prepping thing’.
Let me know if you ever figure out the sourdough secret!
