I just put the cream in a mixer, mix, sample freely as it passes the whipped cream stage, and then put it in a jar. I never remember to salt, but you can in the beginning. You'll end up with buttermilk as well. Some people also rinse the butter so that it will keep longer. I just throw it in a mason jar. And sample freely at the whipped cream stage. It's amazing we ever have butter around here. :msichief
