If required, cut the florets from the cauliflower stems. (The stems are too tough to mash well. Remember: Goal is fluffy.)
Bring a pot of water to boiling.
Place the cauliflower florets and the garlic cloves in the pot and boil for about 15 minutes. The cauliflower is done when you can easily place a fork through it.
Finely chop the chives.
Drain the cauliflower in a sieve or colander. Mind the hot water.
Place the cauliflower, garlic, olive oil, milk, garlic, and onion powder in a food processor (If you don’t have a food processor, use your blender). Mix until your ingredients are smooth and creamy.
Season with salt and pepper to taste.
Sprinkle chives on top prior to serving.
Notes
Tip: After draining the cauliflower, pat all of it dry with a paper towel to remove extra moisture. We want fluffy, not dense, and too much water creates a heavy mash.
