What each ingredient does

Fat
Forms the clear golden base once separated from the water and milk solids.
Water
Carries heat gently during melting and separates the fat from impurities as it cools.

The step that matters

Reheat the fat to drive off moisture. Traces of water left in the fat can cause spattering and shorten its shelf life. Gentle reheating evaporates remaining water so the clarified fat stays clear and stable.
