Delicious Ham and Potato Soup

This is a delicious recipe for ham and
potato soup that a friend gave to me.
It is very easy and the great thing about
it is that you can add additional ingredients,
more ham, potatoes, and it still turns out great.

Ingredients:
3 1/2 cups peeled and diced potatoes
1/3 cup diced celery
1/3 cup finely chopped onion
3/4 cup diced cooked ham
3 1/4 cups water
2 tablespoons chicken bouillon granules
1/2 teaspoon salt, or to taste
1 teaspoon ground white or black pepper, or to taste
5 tablespoons butter
5 tablespoons all-purpose flour
2 cups milk

Directions:
Combine the potatoes, celery,
onion, ham and water in a stockpot.
Bring to a boil, then cook over
medium heat until potatoes
are tender, about 10 to 15 minutes.
Stir in the chicken bouillon, salt and pepper.
In a separate saucepan, melt
butter over medium-low heat.
Whisk in flour with a fork, and cook,
stirring constantly until thick.
Slowly stir in milk as not to allow lumps
to form until all of the milk has been added.
Continue stirring over medium-low
heat until thick, 4 to 5 minutes.
Stir the milk mixture into the stockpot,
and cook soup until heated through.
Serve immediately.
