How do you cut cauliflower?

When you make cuts from the top of the cauliflower head, or curd--as the white clusters are called--things can get messy, with bits of cauliflower everywhere but where you need it.
The neatest way I know to trim up and cut a cauliflower apart is by starting from the bottom.

First, trim off the leaves, which are all at the bottom of the head. Removing the leaves will allow you to see the core of the plant.
Next, with a small knife, carefully cut out the core.
Once the core is out of the head of cauliflower, slice through the underside of the head, through the stem, to separate out the florets.
Keep trimming through the stem of the florets, letting the florets break apart naturally once you reach the curd.

How to make Cauliflower Mashed Potatoes thicker:

Sometimes when I want stand-up-on-the-plate, thick mashed cauliflower, I’ll use some cream cheese blended into the cauliflower give it a little body. If I intend to make a casserole of mashed cauliflower to bring to a party, cream cheese acts as a good stabilizer in the oven, too.

I would add 6 ounces of cream cheese to the recipe, and decrease the butter to 3 tablespoons.

Otherwise, I make sure that the cooked cauliflower is patted dry and the cooking liquid is drained off before mashing.
