Ghee turns cloudy when refrigerated because the fats within it solidify and crystallize as the temperature decreases. This is a natural process and doesn't affect the ghee's quality or flavor.
Ghee is essentially clarified butter, composed primarily of saturated fats. These fats have different melting points. At room temperature, most of these fats are in a liquid state, giving ghee its characteristic clear, golden appearance. However, when ghee is refrigerated, the temperature drops significantly. This lower temperature causes the higher melting point fats to solidify and form crystals. These crystals scatter light, making the ghee appear cloudy or opaque. The degree of cloudiness depends on the specific composition of the ghee, which can vary based on the source of the milk and the production process. The cloudiness is a physical change, not a chemical one, and the ghee will return to its clear state when brought back to room temperature. The process is similar to how olive oil can solidify in the refrigerator.
To minimize cloudiness, store ghee in a cool, dark place at room temperature rather than in the refrigerator, provided your storage environment isn't excessively hot. This will help maintain its clear appearance and spreadable consistency.
