3. Mix in the half and half, the butter, nutmeg and the splash of cooking liquid.
4. Mash with a fork until it's a creamy consistency similar to mashed potatoes.
5. Season with salt and pepper.
6. Continue to use the fork to spread the cauliflower mixture to create a consistent level.
7. Turn on your broiler.

9. Sprinkle evenly over the cauliflower layer.
