What each ingredient does

Fat
Is the medium being clarified, carrying the flavour of the potato and browning in the pan.
Raw potato
Its moisture bubbles off in the hot fat and its slices brown, which helps clear the fat.

The step that matters

Heating the fat gradually. Water from the potato must boil off slowly. If the fat is heated too fast, the potato and milk solids in the fat can scorch and turn bitter, while the fat itself can break down and smoke.
