Oh I love these baking adventures. Sourdough is tricky, but you will get the knack for it soon. Practice and loads of practice. It only gets better with time. I have been doing it for almost ten years now and I have made so many mistakes but mistakes are important to learn!
I love that people are getting back into sourdough baking. It is really awesome. Enjoy the baking! I know the feeling of trying to take photographs when it tastes so good.
