In large saucepan, cook broccoli in 1 cup water; do not drain. Put milk, cheese, and flour into blender; cover and blend until smooth. Add half-and-half and bouillon cubes. Cook, stirring, over medium heat until hot and mixture thickens. Mixture will thicken more upon sitting. Makes 6 cups. NOTE: I like to cut down a bit on the richness this soup has by using 2% milk; and Velveeta "Light" cheese. Keep stirring-as it may burn. Do not cook for more than 25 minutes as it becomes a great cheese sauce after a while-good for pouring over potatoes-but not good if you want soup.
