The best ever homemade potato soup

Okay... I just tried this recipe out last night. I got the base of the recipe from allrecipes.com but I altered it so much that really it ended up being my own.

6 tablespoons butter
1 1/2 C Chopped Onions
1 1/2 C Chopped celery
2 C Water
2 C Chicken Broth
8 Potatoes Peeled and Cubed
1lb sausge
1 12oz (or 3 C) SHARP shredded cheese (I prefer HyVee's)
4 Tablespoons All Purpose Flour
2 1/3 C Milk
2 Tablespoons Fresh Chopped Parsley
A dash of celery salt
1/2 tsp white pepper
salt to taste

In a large pot melt the butter. Saute the onions and celery in the butter until tender. Add the water, chicken stock, and potatoes and bring to a boil. Simmer until they're tender.

In a frying pan brown ground sausage... rinse and drain.

In a seperate bowl mix flour and milk until the flour is mostly dissolved.

When the potatoes are tender add the bag of cheese and stir well until melted. Slowly add the flour/milk mixture and bring to a boil until the soup thickens.

Add the parsley, celery salt, white pepper, and salt. Add in the sausage.

It's absolutely YUMMO!
