Blanched greens (baizhuo) are a classic Cantonese-style way to serve vegetables simply. A quick dip in salted, oiled boiling water keeps the choy sum vivid green and crisp, and a warm sauce poured over top adds savory flavor without masking the vegetable's natural sweetness. The source notes that the root ends of choy sum are tough and should be trimmed first, and warns against over-blanching, which makes the stems lose their pleasant bite.
