Hearty Corn, Chile and Potato Soup

Melt butter in large saucepan over medium-high heat. Add celery and onion; cook for 1 to 2 minutes or until onion is tender. Add water, potatoes, corn, chiles, bouillon, paprika and bay leaf. Bring to a boil. Reduce heat to low; cover.

Cook, stirring occasionally, for 15 minutes or until potatoes are tender. Stir a small amount of evaporated milk into flour in small bowl to make a smooth paste; gradually stir in remaining evaporated milk. Stir milk mixture into soup. Cook, stirring constantly, until soup comes just to a boil and thickens slightly. Season with salt and ground black pepper.
