{{distinguish|text=blanching as a cooking technique}}Blanching is a technique used in vegetable growing. Young shoots of a plant are covered to exclude light to prevent photosynthesis and the production of chlorophyll, and thus remain pale in color. Different methods used include covering with soil (hilling or earthing up) or with solid materials such as board or terracotta pots, or growing the crop indoors in darkened conditions.[1][2] Blanched vegetables generally tend to have a more delicate flavor and texture compared to those that are not blanched,[3][4] but blanching can also cause the vegetables to be lower in vitamin A.[5]Vegetable blanching examplesVegetables that are usually blanched include:[6]

|accessdate=25 August 2011 }} Many varieties do not need artificial blanching because the outer leaves sufficiently protect the inner ones from light, such as 'sugar loaf' types, or because both their natural colour and bitterness are appreciated, like radicchio of which the red colour depends on the duration of exposure. Cultivars that require blanching may need 'forcing' the growth by (controlled) exposure of the crown. This is the case for Belgian endive (though it is a chicory), also referred to by its names in French, ''chicon'', and Dutch, ''witlof''.[7][{{Cite web]
