What each ingredient does
- Active dry yeast
- Ferments the sugars, producing carbon dioxide and the flavour of the starter.
- Potato or hops
- Supplies nutrients that feed the yeast so it multiplies and stays active.
The step that matters
Cool the water fully before adding the yeast. Very hot water kills yeast cells. Letting the boiled water cool to room temperature keeps the yeast alive so it can ferment.
