西蘭花很容易受到蟲害。一般人誤以為應該一朵朵剪開再沖洗，實際上正確的步驟是先準備一盆乾淨的水，加入少量食鹽進行消毒，再加入兩匙麵粉。然後，將西蘭花的頭部朝下浸泡在水中，攪拌沖洗。最後，用清水洗掉這些浮出的蟲卵。

Cauliflower is prone to insect infestation. People often mistakenly think that they should cut and wash each floret individually. In reality, the correct procedure is to prepare a basin of clean water, add a small amount of salt for disinfection, and then include two tablespoons of flour. Submerge the cauliflower head down into the water, stirring and rinsing. Finally, wash away the emerged insect eggs with clean water.
