Making your own butter is simple and rewarding – nothing tastes quite as good as homemade.  Just put heavy cream in your blender or food processor for about 10 minutes, or until the butterfat separates from the buttermilk (mine took a little less than 10 minutes).  Once you’re there, you’ve got fresh unsalted butter.  But why on earth would you stop now?  Jazz it up with thyme, sage, honey, cayenne pepper, or, as the video shows, add some chopped porcini mushrooms and black truffle salt. 

Oh, and whenever you’re working with small appliances, be sure to wear your geek glasses for protection
