What each ingredient does

Flour
Provides starch and nutrients that feed the yeast and thicken the liquid.
Brown sugar
Gives the yeast a quick food source and adds a mild molasses flavor.

The step that matters

Cooling to milk-warm before bottling. If the mixture is still hot, it can kill the yeast when it is added later. Cooling it to milk-warm keeps the environment gentle enough for live yeast to survive and begin fermenting.
