Ham and Potato Chowder

I saw a recipe in a book that had a good basis for a soup.  I took it and completely transformed the recipe to come up with this one.  My kitchen smelled AMAZING while it was cooking!!!  I'm going to make a second batch and freeze it for our camping trip in a couple of weeks!  Hope you like it!

Ingredients:
4 cups of potatoes, peeled and diced
2 celery stalks, chopped/diced into small pieces
1/3 small onion, diced
1 1/2 cups of diced ham
1 can corn
3 1/2 cups water
3 bouillon cubes, chicken flavor
1/2 tsp salt
1 tsp pepper
1/2 tsp onion powder
5 Tbsp soft butter
5 Tbsp flour
2 cups milk

Directions:
*Put potatoes, celery, onion, water, corn and ham in a large stock pot.  Cook on MEDIUM for about 30-35 minutes.  Cook until the potatoes are soft.

*Once the potatoes are soft, add the bouillon cubes, onion powder, salt, and pepper.  Stir well and continue cooking until the bouillon cubes are completely dissolved.

*In a separate small pot or pan, cook the butter on medium to medium-low heat until it is melted (make sure to stir constantly so the butter doesn't burn).  Add the flour to the melted butter and whisk it until it is completely combined.  VERY SLOWLY add the milk.  Make sure NOT to get the mixture lumpy.  Stir the mixture constantly as you are adding the milk.  Once it is all combined, continue cooking 3-4 minutes until it has thickened a bit and is hot.

*Add the milk mixture to the potato and ham mixture.  Stir it all well and continue cooking a couple of minutes until it is heated through.
