In professional kitchens and home cooking alike, the technique of blanching vegetables—particularly leafy greens—is both an art and a science. The golden rule for preserving the vibrant color and crisp texture of greens is simple: 30 seconds in boiling water, no more. Exceed that window, and the chlorophyll breaks down, leaving behind a dull, olive-toned shadow of what was once a bright, fresh ingredient.
