I was never a fan of “sourdough” bread, although Peg loves it. Always up for a challenge (and nice guy that I am) I tried to make some.
Retired as I am, I have plenty of time to watch videos on YouTube, hundreds, if not thousands of which are on the subject of baking sourdough bread. The YT channel that most resonated with me was ChainBaker, a bloke named Charlie who taught me how to make the starter from just water and flour, to making some pretty good bread.
I don’t try to get the bread really sour, per se, rather I use the wild yeast to do the leavening. And I am still learning how to control how the bread comes out.
