Classic Corn Chowder

In a large pot over medium heat, cook bacon until crisp. Remove bacon onto a paper-towel lined plate. Drain all but one tablespoon fat and cook the onions until translucent, about 4 minutes. Add potatoes and chicken stock and bring to a boil. Reduce heat, cover, and simmer for about 10 minutes, or until the potatoes are tender. When potatoes are tender, whisk flour into milk, then stir that mixture into the pot. Add corn, cream, cheese, and bacon (reserving some for topping, if desired) and bring soup back to a boil, cooking until cheese is melted, 2 to 3 minutes more. Season with salt and pepper to taste, and garnish with chives before serving.
