Clarified butter
This is butter that has had the whey and the milk solids removed which allows the butter to be heated to a higher temperature without burning.
To make clarified butter:
Heat the butter in a saucepan over medium heat. As it melts, the butter will start sizzling as the water evaporates and the butter breaks up in three layers. A sediment will form in the base of the pan, a froth will form on top and the clear butter in the middle. The sediment on the bottom should not go brown in the process and the froth on top has to be skimmed. Pour the butter through a sieve lined with cheesecloth to trap the milk solids. Store the clarified butter covered in the refrigerator for up to 3 weeks or freeze it for 3 months.
When the recipe calls for foaming butter, do not use clarified butter because the impurities that you remove when clarifying, is in fact, what encourages the foaming.
