**If you are looking to freeze your own cauliflower at home, you will need to blanch the cauliflower florets first. Bring a pot of water to a boil and slice up the cauliflower into florets. Have a large bowl of ice water waiting on the side. Toss in the florets and boil for 2 minutes. Remove with a strainer ladle (or something similar) and let sit in the ice bath for 2 minutes. Remove from the ice and place on a baking sheet lined with parchment paper. Lay the florets out in an organized fashion (not touching) and pop in the freezer to set for about an hour or two. From there you can place into a freezer-safe bag (i recommend these).
