Dragon's beard candy (or Chinese cotton candy) is a handmade traditional art of Ancient China. It is also a traditional Chinese sweet similar to spun sugar, which can be found in many Chinese communities. Dragon's Beard Candy was initially created in China, but soon spread in popularity and became a regional delicacy in other parts of East Asia, as well as (and more recently) Canada, Singapore, the United States, Taiwan, Hong Kong, and Japan. Dragon's Beard Candy is a highly prized sweet within the Korean royal court as well.
