It was in ancient China, in early Han times (202 BC-AD 220), that the delicately flavored shoot was discovered as a food. It is the tender young shoot of an edible bamboo plant from about 6 inches (15 cm) high. The creamy young shoot is considered a great delicacy in winter, having a more pronounced flavor than the spring bamboo shoot, which is more delicate in taste but possesses a crunchier texture.
