What each ingredient does
- Mashed potatoes
- Provide starch that feeds the yeast and adds body and moisture to the starter.
- Compressed yeast
- Ferments sugars and produces gas, causing the starter to rise and become active.
- Sugar
- Serves as food for the yeast, speeding fermentation and adding a little sweetness.
