  1. Make a thin gruel with the spring water and flour, stirring and boiling for 20 minutes.

  2. Add the sugar when the mixture is warm, about the temperature of fresh milk.

  3. Stir in the fresh yeast, cover, and let it ferment in a warm place, removing the yeast as it rises.

  4. Keep a few spoonsful corked in a bottle for future use.

What each ingredient does

Flour
Forms the thin gruel that feeds the yeast and gives the starter its body.
Sugar
Provides food for the yeast, driving fermentation.
Fresh yeast
Acts as the living culture that ferments the mixture and raises it.

The step that matters

Add the sugar when the mixture is warm, about the temperature of fresh milk.. The mixture must be warm but not hot, since yeast is killed by excessive heat. Adding sugar at this temperature lets the yeast start fermenting quickly and safely.
