Gai lan
A leafy vegetable with thick stems and a stronger, bitter flavor than broccoli.
Gai lan, also known as kai-lan, Chinese broccoli, or Chinese kale (Brassica oleracea var. alboglabra), is a leafy vegetable with thick, flat, glossy blue-green leaves, thick stems, and florets similar to but much smaller than broccoli. It is a Brassica oleracea cultivar in the group alboglabra, from Latin albus 'white' and glabrus 'hairless,' and when gone to flower, its white blossoms resemble those of its cousin Matthiola incana or hoary stock. Its flavor is very similar to broccoli but noticeably stronger and slightly more bitter.

Lore & Background
Gai lan is a cool season crop that grows best between 18 and 28 °C (64 and 82 °F) and withstands hotter summer temperatures better than other brassicas such as broccoli or cabbage. It is harvested around 60–70 days after sowing, just before the flowers start to bloom; the stems can become woody and tough when the plant bolts. It is generally harvested for market when 15–20 cm (6–8 in) tall, but can also be produced as 'baby gai lan' through crowding of seedlings and generous fertilization, which resembles Brussels sprouts although it has looser folds. Broccolini is a hybrid between broccoli and gai lan. The stems and leaves of gai lan are eaten widely in Chinese cuisine, with common preparations including stir-fried with ginger and garlic, or boiled or steamed and served with oyster sauce. It is also common in Vietnamese, Burmese, and Thai cuisine, and in Chinese cuisine it is often associated with dim sum restaurants. In Americanized Chinese food, such as beef and broccoli, gai lan was frequently replaced by broccoli when gai lan was not available.
Reader's Guide
Gai lan holds significance as a distinctive leafy vegetable in East and Southeast Asian cuisines, particularly Chinese, where it is a staple in both home cooking and dim sum restaurants. Its stronger, slightly bitter flavor compared to broccoli sets it apart, and its ability to withstand hotter summer temperatures makes it a resilient crop for growers. The development of broccolini as a hybrid between broccoli and gai lan demonstrates its genetic utility in modern agriculture. The vegetable's legacy includes its adaptation in Americanized Chinese food, where it was often substituted with broccoli due to availability, highlighting its role in culinary exchange. As a cool season crop harvested before flowering, gai lan requires careful timing to avoid woody stems, and its 'baby' version offers a different texture and presentation. Its white blossoms, resembling hoary stock, add an ornamental aspect. Overall, gai lan remains a key ingredient in diverse Asian cuisines and a subject of horticultural interest.
