Key ideas in Sourdough from Scratch
- Wild yeast and bacteria are naturally present and alive
- Visible bubbles indicate carbon dioxide production
- Flour provides the necessary sugars for the microbes to eat
- A tangy, fruity, or yeasty smell is a sign of good fermentation
- The mixture is a self-sustaining ecosystem, not a chemical reaction
- A flat, liquid surface with no bubbles indicates dormancy or hunger
- Understanding that a starter is a living biological community requiring food
- Identifying the sensory signs of a healthy, ready-to-use starter
- Keeping all the old starter requires exponentially more flour to feed it
- Heat speeds up the metabolism of yeast
- Discarding prevents the jar from overflowing
- Refrigeration is the best way to 'pause' a starter for a week
- Using temperature to manage the timeline of starter activity
- Floating indicates the starter is full of trapped gas
- The practical purpose of discarding starter during the feeding process
- Sinking means the starter hasn't peaked or has already collapsed
