What each ingredient does

Yeast
Ferments the sugars and produces gas that makes the starter rise and become bubbly.
Mashed potatoes
Provide starch and body, feeding the yeast and thickening the starter.
Sugar
Gives the yeast an easily used food source to speed up fermentation.
Coarse sea salt
Controls yeast activity so fermentation proceeds steadily rather than too fast.

The step that matters

Cover and let rise overnight. The starter needs a long, undisturbed fermentation for the yeast to multiply and develop flavor. Covering it keeps the surface from drying and crusting, which would stop the rise.
