What each ingredient does

Hops
Adds bitterness and aroma that balance the sweetness of the malt.
Malt
Provides the sugars that the yeast ferments into alcohol and carbon dioxide.
Patent yeast
Ferments the sugars from the malt, producing alcohol and carbon dioxide.

The step that matters

Adding the yeast at blood heat. Yeast is killed by very hot liquid, so the mixture must be cooled to about body temperature before adding it. Too hot and the yeast dies; too cold and fermentation starts slowly.
