the.com/blanch
a violent dunk in boiling water that locks color in by stopping a vegetable's slow self-destruction.
means To briefly plunge food (usually vegetables) into boiling water and then into ice water, setting color and texture; or, of a person, to turn pale with shock or fear.
from From Old French 'blanchir,' to whiten, from 'blanc,' white — itself borrowed from a Germanic root 'blank,' meaning bright or shining (the same family that gives us English 'blank,' once 'pale' or 'colorless'). So to blanch was first simply to make white: the kitchen sense, where heat blanches food, sits right beside the human one, where a frightened face goes white in an instant.
