What each ingredient does

Fat scraps
Provide the rendered fat that is clarified into a clear, pure cooking fat.
Cold water
Gently heats the fat and evaporates away, leaving only the melted fat behind.

The step that matters

Boil gently with the lid off until the water has evaporated. Water in the pan keeps the temperature near boiling while it cooks off. Only once it is gone can the fat rise above that point and render cleanly. Rushing with high heat or leaving the lid on can let the fat spatter, scorch, or stay cloudy with moisture.
