Easy Potato Soup with Rivvels

Growing up, if we needed a quick meal, this was a go to dish.  To make:

Cube potatoes - enough for as many people as you want to feed.  Peeling is options.  Boil potatoes in water until soft.  Drain, return to pan and just cover with milk.  Add 1 Tbl butter for each person.  Heat over low heat until hot and just starting to simmer.  Drop rivvel dough into hot liquid by fork full and simmer until cooked.  Add salt and pepper to taste and serve.

To make Rivvels:

Mix 1 cup flour, 1 egg and just enough water to make a stiff dough.
