My children did this the past two years, so I guess it's on its way to becoming a family tradition. It's super easy and gives everyone a chance to have a turn. They are so proud to pass "their" butter around the table. I could go into the details, but one of the blogs I follow, My Montessori Journey, has a post with directions and pictures. Why reinvent the wheel? Enjoy and I hope this becomes a tradition in your home, too!
