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
 
Instruction
- Combine the potatoes, celery, onion, ham and water in a stockpot. Bring to a boil, then cook over medium heat about 10 to 15 minutes until potatoes are tender. Stir in the chicken bouillon, salt and pepper.
 - In a separate saucepan, over medium heat melt butter. Whisk in flour with a fork, and cook, stirring constantly until thick, about 1 minute. 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.
