Autumn Potato Soup

Ingredients: Directions:
Place potatoes, onion and water in a heavy saucepan, and bring to a boil. Simmer, covered, until potatoes are tender. Remove from heat and mash potatoes a bit; stir in milk. Mix butter and flour together till no lumps remain; (I use a little tiny whisk) add to potato mixture. Cook over medium heat, stirring constantly, until thickened. Remove from heat and stir in cheese.
