Baked Potato Soup

This recipe was pretty close to the way I do it (you all know I don't use recipes) so here ya go!

2/3 cp butter or margarine
2/3 cp all purpose flour
7 cps milk
4 large baking potatoes, baked, cooled, peeled and cubed (about 4 cps)
4 green onions, sliced
12 bacon strips, cooked and crumbled
1 1/4 cp shredded cheddar cheese
1 cp (8 oz) sour cream
3/4 tsp salt
1/2 tsp pepper

In a large soup kettle, melt the butter. Stir in flour; heat and stir until smooth. Gradually add milk, stirring constantly until thickened. Add potatoes and onions. Bring to a boil, stirring constantly. Reduce heat; simmer for 10 minutes. Add remaining ingredients; stir until cheese is melted. Serve immediately. Makes 2-1/2 quarts.
