What each ingredient does

Scraps of fat
Supplies the rendered fat, which is the main product of this method.
Cold water
Gently heats the fat and carries off moisture as it evaporates, leaving clean fat behind.

The step that matters

Boil gently with the lid off until the water has evaporated. Water must fully boil away before the fat can clarify. Leaving water in would stop the fat from becoming clear and could cause spattering. A gentle boil renders the fat without scorching it.
