Strain the clarified butter through a fine mesh sieve or a piece of cheesecloth to get rid of any remaining milk solid bits. Store the clarified butter in an airtight container, and refrigerate. The clarified butter will keep in the fridge for three to six months.
Remember: Just because it's called clarified butter doesn't mean it will always look clear. The clarified butter will appear clear and liquid-y when it is hot and will transform to a cloudy, dense paste when it is at room temperature or refrigerated.
