The technique for clarifying butter is very easy. Simply melt butter over low heat and allow it to simmer until all the solids fall to the bottom of the pan: this may take a little time but don’t be tempted to leave it unattended or it could burn. Decant the butter into sealable containers and it will keep for months refrigerated. Clarified butter’s principal use is for frying, since with the solids removed it can withstand higher temperatures without burning, unlike fresh butter.
