What each ingredient does

Drippings
Provide the fat that becomes the clarified butter, with milk solids and impurities removed.
Boiling water
Boils off to drive out moisture, leaving behind pure fat that is ready to strain.
Baking soda
Neutralises acids in the fat, helping impurities separate so the fat clarifies cleanly.

The step that matters

Boil until the water has completely evaporated. Any water left in the fat makes it cloudy and can cause spattering, and it spoils the fat sooner. Boiling off all the water leaves pure fat that stores well.
