I love this display of cauliflower at a market I went to recently - like basketballs tumbling out of their bin onto a gym floor, ready to be played with. In the case of cauliflower that "playing" takes the role of cooking, of course. Cauliflower is, in my estimation, one of the great unsung vegetables. It's super versatile and will last approximately forever when properly stored, which means it's a great way to always have fresh vegetables in the house.
Check out All About Cauliflower to learn about buying (look for firm heads and cauliflower that feels heavy for its size), storing (loosely wrapped in the fridge), and cooking (Cauliflower Fritters, Cauliflower Pakora, and Spicy Roasted Cauliflower are all favorites at my house, as are Cauliflower Soup, Cauliflower Pasta, and Cauliflower Gratin) cauliflower.
