What each ingredient does

Coarse moist sugar
Provides the sugars that yeast converts into alcohol, which then becomes acetic acid.
Yeast
Ferments the sugar solution, producing alcohol that bacteria later turn into vinegar.
Cream of tartar
Adds acidity that helps keep the mixture stable during fermentation.

The step that matters

Skimming the boil. Foam that is left on the surface can carry impurities and off-flavours into the fermenting liquid, so removing it during the boil gives a cleaner-tasting vinegar.
