This is the traditional New Year's Day meal I learned from my husband, whose family originated in central Pennsylvania. It's wonderful, especially served with mashed potatoes and applesauce.
Shredded potatoes and grated onions are bound with flour, salt and eggs, then fried in oil to make delicious potato pancakes that are crispy on the outside and tender on the inside.
Bake the potatoes and shred the cheese the day before making the soup. If the soup needs to simmer awhile on the stove, you may need to add more chicken broth.
