Hey Sea - golly I have walked much the same path. Both water kefir and sourdough starter have been uphill roads with many detours.
I have come to the conclusion that sourdough can be something to gradually sidle up to.... just getting the starter to be consistently happy, but not so exhuberant that it overflows, has been more like managing a bipolar lab creature than working with a reliable and welcome kitchen ingredient. When it is unhappy, I end up refreshing it more often in my bumbling attempts to improve, and then I have sourdough discard, which can go to the chickens mixed in their fermented grains, but I like to make productive use of it.
My favorite use of the discard is to make crumpets (here is an example
https://www.scotchandscones.com/sourdough-crumpets/ ) especially currently, while I am glamping with very limited baking options while tiny home is in construction. Until I get the RMH oven finished and functional, I am really appreciating the capacity to make some version of bread on a cast iron skillet.
and in all honestly, as someone who lives solo, a perfect loaf is very seldom my objective. It takes a while for one person to get through a full loaf of bread... honestly longer than it stays wonderful, and freezing then thawing does NOT provide the same eating experience.
So maybe I am in sourdough kindergarten.... taking little steps!
