After a week of feeding the starter, I figured it was time to make a loaf and see how it turned out! The bread was mostly a success, the failures were on my part while baking and I don't think were related to the starter. I did half AP and half whole wheat flour, and too much hydration (I miscalculated the water)- the dough was pretty sticky and I had some trouble with it sticking to the tea towel I used to line the "proofing basket" (I used a mesh colander). I did a cold proof overnight in the fridge (recommended by a lot of the videos/recipes I read) before baking, and baked in a dutch oven. I forgot to turn down the heat after taking the lid off the oven for the second half of the baking, so the crust got dark way too quickly so it was a little underdone in the center.
All in all, I'm ok with how it turned out! It wasn't quite as sour as I was hoping for, so my next goal is to figure out how to get it more fermented next time. Here are some photos!
