Candy apples, also known as toffee apples outside of North America, are whole apples covered in a hard toffee or sugar candy coating, with a stick inserted as a handle. These are a common treat at autumn festivals in Western culture in the Northern Hemisphere, such as Halloween and Guy Fawkes Night because these festivals fall in the wake of the annual apple harvest. Although candy apples and caramel apples may seem similar, they are made using distinctly different processes. (source)
