Steam cauliflower over boiling water until fork-tender, about 15 minutes. Do not boil cauliflower or use frozen florets as they will be too watery.
Drain off any excess water and place cauliflower in blender or food processor along with the butter, sour cream, salt, pepper and garlic powder (if desired). Blend until smooth and creamy.
Top with chives or other fresh herbs such as parsley or dill.
