Melt the butter slowly and let it sit to cool & separate. Skim off the foamy top and gently pour the butter off of the milk solids, which will settled to the bottom.
You can also strain off the solids through a cheesecloth or coffee filter.
You'll get about 75 % clarified butter back from your original amount- so 1 cup of butter will net about 3/4 cup of clarified butter (roughly).

Keep in mind that if you don't have the patience to do this yourself, and like to have clarified butter on hand, you can often purchase it at health food stores. It keeps unrefrigerated for months.
