How do you properly wash cauliflower before cooking it?

To properly wash cauliflower before cooking, first remove the leaves and cut off any brown spots. Then, rinse the cauliflower under cold running water, making sure to clean between the florets. You can also soak the cauliflower in a bowl of water with a splash of vinegar for a few minutes to help remove any dirt or insects. Finally, pat the cauliflower dry with a clean towel before cooking.
