blanch

What does "blanch" mean?
To "blanch" is to briefly immerse a food item, such as a vegetable or nut, in boiling water and then quickly transfer it into ice water. The mental image is a sudden shock of heat followed by a cooling plunge, which serves to loosen skins, brighten colors, or stop the cooking process for later use. In a broader, more literary or metaphorical sense, "blanch" also means to turn pale or white, often due to a sudden shock, fear, or intense emotion. While the culinary usage is common in kitchens, the emotional usage is typically found in novels or formal descriptions of someone's reaction to bad news or a frightening sight.
