Take cream off the top of milk. Add a quart to a half-gallon of cream to a Bosch Mixer or 1 pint to a Kitchen Aide mixer and turn it on low. Watch and listen for the cream to turn to butter. This can take an hour with winter cream. After the cream turns to butter (there’s usually a change in the sound of the mixer), you will notice there are chunks of butter mixed with buttermilk (looks like thin milk). Simply strain off the buttermilk and then form the butter into a ball and kneed it with your hands or a paddle until most of the buttermilk is out. It helps to rinse it with cold water a few times as you are kneading. After most of the buttermilk is removed, salt it, let it sit for several minutes (allowing the salt to pull more liquid) and then work it again until no milk comes out.
