This is a traditional PA Dutch recipe that I have every year on New Years Day. The reason we ate pork and not chicken is because when a pig digs, he moves dirt forwards, and when a chicken digs they move dirt backwards. We want the New Year to be "looking forward" like the pig. The roast cooks on LOW for 8 hours in the crock pot and it is served with mashed potatoes. We always ate it with the mashed potatoes on the plate - make a well in the potatoes and the pork and sauerkraut go on top. Each bite needs all three things on the fork.
Happy New Year!
