Place the cauliflower florets in a small pot, and fill with water. Place over medium heat and cook until the florets are fork tender. Save around 1/4 cup cooking water and discard the rest.
Transfer the cauliflower florets to a blender with the cooking water and pulse. Add the milk, salt, and pepper. Pulse until creamy.
Transfer to the pan with the melted ghee. Cook for 3 minutes.
Toss over pasta. Top with parmesan cheese. Enjoy!
