In my personal experience , I have find out that parboil is a of the essence step in acquire high - tone cauliflower . I have had case where I neglected to parboil my cauliflower plants , and the head turn green and developed a bitter tasting . It was unsatisfying to see the beautiful ashen heads I had anticipated turn into unappealing green - yellow formation .
To keep off this , I now verify to carefully parboil my cauliflower plants as soon as the nous start to mould . By need the extra effort to protect the head from sunlight , I have been able to love delicious and visually appealing cauliflower that keep its natural white gloss .
To summarize , cauliflower heads turn unripened when they are exposed to direct sunshine , which triggers the production of chlorophyl . Blanching is the proficiency used to prevent this by turn out sunlight from the develop heads . By creating a shade or barrier using the out leaves , blanching helps maintain the desire white-hot color and enhances the taste of cauliflower .
