I've made a few more sourdough loaves and have fine-tuned my technique. It's denser and softer than sourdough "should" be according to social media, but I like it that way. I was intimidated because many of my gal pals were showing me horrifying photos of their first loaves, talking about how they struggle to get their dough to rise, etc etc but when I got to it myself it really wasn't that hard. I don't understand how, in the age of the internet with detailed recipes right at your fingers, people fuck it up unless you get distracted by something.
Anyway I plan to try mixing in some additional ingredients during stretch and folds next time. Like cheddar cheese and chili oil, or chocolate chips and freeze-dried strawberries.
