Why are cauliflower leaves tied over the head?
Only pure white cauliflower attracts good prices. The curd of cauliflower will develop a cream color, or even a green color, if it is exposed to long periods of sunlight. Leaves are tied over the head to provide protection from the sun. This is called blanching. Self blanching types have been developed that have upright leaves which protect the head without tying.
