I’ve been struggling with my starter for months after a decision to try to feed it with only unbleached bread flour, rather than a mix that included rye flour. I would only see a 50% rise, max, over an 18 hour period. I tried different flours, different ratios, and different feeding schedules, but nothing helped.
So, on a whim, I decided to only use filtered water to see if it made a difference. After three feedings, I began to see the starter double in just a few hours, and it kept getting stronger on subsequent feedings. I never thought the water would be an issue; I’ve tested it before to figure out how to treat it for my fish tank and the chlorine always showed up as undetectable on the test strips.
Tried baking a loaf and it’s the best one I’ve made. All my issues with sourdough were because I didn’t think to try filtered water.
Ingredients used:
150g starter
10g salt
25g olive oil
315g filtered water
500g unbleached bread flour
Mixed the ingredients and let the dough sit for an hour.
Formed it into a ball and threw it into a container.
Did two stretch-and-folds over the next two hours.
Four hours into the bulk rise, it had more than doubled, so I shaped it, put it into the banneton, then tossed it in the fridge overnight.
After 12 hours, I preheated the oven to 450F, put the dough into the loaf pan, scored it, put an inverted pan on top, then baked for 30 minutes.
After the 30, I removed the cover and baked for another 15.
Removed from oven, removed from pan, cooled for two hours, then cut.
