What each ingredient does

Coarse sugar
Provides the sugar that the yeast converts during fermentation, producing the sour acids of the vinegar.
Yeast toast
Supplies the yeast and microbes that start the fermentation of the sweet liquid.

The step that matters

Let the mixture cool before adding the yeast toast. Yeast cells are killed or weakened by heat, so adding the yeast to hot liquid can stop fermentation before it starts. Cooling first keeps the culture alive to begin converting the sugar.
