This is a real favorite in my house! It is easy to make and doesn't take very long to make. By no means is this a "Low-Calorie" soup, but it really sticks to your ribs and warms you up in cold weather!! Once you start to make this soup, it is ready to eat in about an hour!
In a saucepan, cook bacon and add onion...Cook until browned, reserving drippings. Cut the heat and add diced celery. Set aside.
In a large pot, add cubed potatoes and cover with the water. (Add more to completely cover the potatoes if needed.) Cook the potatoes until tender. Add bacon, onion & celery mixture. Be sure and add at least most of the bacon drippings too. (This is where a lot of the flavor is.) Stir together.
When the liquid is hot, add the chicken bullion to make a light but savory chicken broth. Add milk and butter. Heat to just under boiling temperature and add the flour & water mixture and whisk in to thicken the soup. Thicken it to as thin or as thick as you like. Add pepper to taste. This shouldn't need any salt... add if needed.
Reduce heat to low and let simmer for about 15 minutes and thin with a little more milk or water if it gets too thick. Serve hot with crackers. (Garnish with some 'real bacon bits', shredded cheese and chopped green onion tops sprinkled on top of each bowl - OPTIONAL)
