;It depends upon your specific machine. Some cotton candy machines require floss sugar, while others can handle superfine or even granulated sugar. A handful of machines work with hard candy, as long as it’s made with corn syrup, and chopped or crushed. Peppermint cotton candy could make a delightful Christmas party treat, and Jolly Rancher, butterscotch, or cinnamon cotton candy raises some intriguing possibilities. Be sure to check your manufacturer’s instructions for its specific requirements, because sticky sugar of the wrong sort could wreak havoc on your machine.
