Fry diced bacon until crisp, remove from pan. Add minced onion and celery to bacon grease and saute until limp. Combine above in slow cooker pot with water, boullion, potatoes, margarine and cream style corn. Cover and cook on low 7 to 9 hours. Add milk and cream, cook half hour more or until heated through.
Notes: Can use chicken stock to replace water and bullion cubes. Mocha mix makes this soup extremely rich tasting, and the Mocha mix does not curdle with high heat like regular milk or cream. Can also be made on the stovetop. Instead of placing in the slow cooker, simmer on the stovetop until potatoes are tender. Add the milk, cream and heat through. Serve immediately.
