It is not necessary to blanch, cauliflower before frying blanching is to remove the smell of cauliflower and when the cauliflower cooked faster.

Cauliflower (scientific name: Brassica oleracea L. var. botrytis L.), also known as cauliflower, cauliflower, coconut cauliflower, kale, broccoli, bulbous kale. It is a vegetable of the cruciferous family, an annual plant, and a variant of kale along with broccoli and balled kale.

The head of cauliflower is a white inflorescence, similar to that of broccoli. Cauliflower is rich in vitamins B complex and C. These components are water-soluble and are easily dissolved and lost by heat, so boiling cauliflower should not be cooked at high temperatures and is not suitable for boiling. Native to the Mediterranean coast, it was introduced to China around the beginning of the 19th century during the reign of Emperor Guangxu of the Qing Dynasty. Its product organs are white, short shrunken, fat and tender flower buds, flower branches, flower shafts and other polymerization of the flower ball, is a kind of crude fiber content is small, the quality of tender, nutritious, flavorful and delicious, people like to eat vegetables. White cauliflower and green cauliflower nutrition, role is basically the same, green cauliflower than white cauliflower carotene content is higher.

Cauliflower fertility habits like cool, is a half-hardy vegetables, its heat and cold resistance are not as good as the ability to nodding kale, neither high temperature drought, but also intolerant of frost. Fertility temperature is relatively narrow, cultivation of environmental conditions are more stringent, which is mainly determined by the botanical characteristics of cauliflower.

Because the product organ of cauliflower is a shortened flower branch, flower axis, buds and other polymerization of the flower bulb, the flower bulb is both reproductive organs and nutrient storage organs.

Biologically speaking, the reproductive stage of any organism is the weakest stage of vulnerability, so cauliflower in the growth and development of the flower bulb of the period of high temperature, drought, frost and other adverse environmental conditions of the ability to resist poor; from the reproductive habit of cauliflower, the polymerization of the flower bulb as a nutrient storage organ, the appropriate environmental conditions of cauliflower from the nutrient growth to the reproductive growth, to go through the flower bulb as a carrier for the nutrient accumulation and storage process. Nutrient accumulation and storage process, so that the flower bulb fully grown and firm. If cauliflower at this stage, the external conditions beyond its own suitable range, such as high temperature and drought, the above process will be shortened, and its shortened flowering branches in the high temperature will be rapidly elongated, thus making the ball small and loose, cultivation will not get a satisfactory harvest.
