Katherine's Potato Soup

This post is especially for my friend, Dola.  She had her gall bladder removed a few weeks ago, and I took her this potato soup.  This is from memory, and I never follow a recipe when I make this, but it should be pretty close.  :)

1.  Boil about 5 lbs of peeled and diced potatoes until fork-tender.
2.  Cut up about 1/2 lb of diced carrots.  Cook them separately, since they cook differently than potatoes.
3.  Cook 1 package of bacon (I used turkey bacon).  Cut the bacon into small, bite-sized pieces.
4.  Make a roux by blending about 3 tbsp. oil or melted butter with about 3 tbsp. white flour.  Then add 3 cups of milk all at once and whisk it continually until the mixture thickens.
5.  After the potatoes and carrots and bacon are done, drain the potatoes and carrots and add them all to a big pot and add the white sauce.  Add about 3 more cups of milk, salt and pepper to taste, and 1 can of creamed corn.  Stir until heated through and the milk/white sauce is well blended.
6.  Add 2-3 cups grated cheese.  Stir until melted and well blended.
7.  Eat!
