Gai Lan
Gai lan is a leafy green cruciferous vegetable native to China, prized in Asian cuisines for its slightly bitter, sweet flavor and tender stems. Unlike broccoli, gai lan features elongated flowering heads with large leaves and thin, edible stalks that are more tender than the vegetable's name suggests. It is a staple in Cantonese cooking and increasingly popular in modern Western kitchens for its nutritional density and versatility in stir-frying.
