What is "barley sugar"?

Barley sugar is a type of hard candy that is made by boiling sugar and water together until it reaches a high temperature and forms a thick syrupy consistency. The candy is then flavored with barley malt extract, which gives it a distinctive sweet and slightly nutty flavor. Barley sugar is often formed into long, thin sticks, which can be twisted or curled into various shapes. The candy is also sometimes flavored with additional ingredients, such as lemon or honey. Barley sugar has a hard, brittle texture that melts slowly in the mouth, making it a popular candy for people who enjoy a long-lasting, sweet treat. It is often enjoyed during the winter months and is a popular candy in the United Kingdom. Barley sugar can also be used as a sweetener in tea or other hot beverages.
