For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Building and Handling Living Dough and Timing, Shaping, and the Bake. It starts from scratch.

Key ideas in Baking Sourdough at Home
- A sourdough starter is powered entirely by equal parts flour and water
- Wild yeast and beneficial bacteria already live in flour and the environment, so commercial yeast or sugar are unnecessary
- A starter at its peak has doubled or tripled in volume compared to its starting line
- A domed surface signals it is still holding maximum gas, whereas a sunken top means it has collapsed past peak
- Placing a rubber band around the jar right at the freshly fed starter line provides a baseline
- Straight vertical jar walls make it easy to see exactly when the starter has reached twice its original height
- Cold refrigerator temperatures chill yeast and bacteria into dormant hibernation
- A refrigerated sourdough starter only needs maintenance once a week instead of daily counter feedings
- Without discarding, the volume of starter snowballs exponentially and wastes massive amounts of flour
- Removing old starter prevents harsh acidic buildup that eventually weakens the wild yeast
- Flour and water start forming gluten bonds on their own simply by hydrating, without any physical kneading
- Adding starter later allows enzymes to break down starches and soften the flour first, making the dough stretchy effortlessly
- High-hydration sourdough dough is too wet for aggressive countertop pounding, which just sticks to hands and tears gluten
- Gentle stretch-and-folds directly in the bowl easily align and strengthen wet sourdough strands
- Early sourdough dough feels slack, flat, and puddles in the bowl
- Repeated periodic folds pull the dough upward into a smooth, dome-like mound with surface tension
