Butter Soup

This recipe I received from a swap. I haven't had a chance to make it but I would like to soon.

8 cups water
6 potatoes, cubed
1 yellow onion
1 Tbsp butter
1 bay leaf
2 tsp dried parsley
salt to taste ground
black pepper to taste
1 cup all purpose flour
2 eggs
1/2 cup half and half cream

Quarter the onion and separate the layers. Boil 8 cups water with the potato, onion, butter, bay leaf, parsley, salt and pepper to taste. When the potatoes are done, mix the flour, eggs and about 1 tsp salt in a separate bowl. Add water until it is a thick dough. Spoon or cut noodles into soup--I tilt the bowl over the soup and use a butter knife to cut strips as it pours. AFter noodles are fluffy, pour in the cream. Heat and serve. This soup is even better the next day.
