Place in large pot potatoes, green beans, water, and bullion. Bring to a boil for about 10 minutes or until potatoes are tender. Meantime, mix 1 cup flour, egg, and enough cream to make a sticky dough mixture. Drop by small spoonfuls into boiling soup. They float when done. Cook flour and grease/butter for 1 minute and add the remaining cream and mix into a slurry. Add this to the soup to thicken up.
