Cauliflower heads are always white because they grow and mature completely covered by their leaves. Farmers tie the largest outer leaves of each cauliflower plant. This protects them from direct sunlight, leading to no chlorophyll development – the green pigment present in many vegetables.
How did cauliflower become white?
White cauliflower matures creamy white if the head is void of direct sunlight. Older cultivars need to be blanched (inner leaves are tied loosely over the small heads to reduce the amount of light penetration) to prevent the sun from turning white cauliflower to yellow.

What happens if you don’t blanch cauliflower?
Does cauliflower have to be blanched? Technically, no. Blanching has nothing to do with head development or nutritional content. However, if you don’t, the curds will be greenish brown rather than white and the flavor will be stronger, almost bitter.
Did humans make cauliflower?
Yes! Cauliflower is a man-made vegetable that has been purposefully modified by humans for generations. It is the cultivar of wild cabbage and is the product of careful selection and breeding. This has also led to the birth of other popular vegetables in the same family as well.
Why blanching is done?
Blanching stops enzyme actions which otherwise cause loss of flavor, color and texture. In addition, blanching removes some surface dirt and microorganisms, brightens color and helps slow vitamin losses. It also wilts greens and softens some vegetables (broccoli, asparagus) and makes them easier to pack.
