If using a 1-pound box of sugar, it is possible to create approximately four servings on cotton candy. The number will vary based on the recipe that is used.
In a recipe posted by one of Food Network's chefs, it is possible to make 10 servings of cotton candy with five cups of granulated sugar. Other ingredients include corn syrup, water, flavored oil, food color paste and cooking spray.
It is also important to have the right tools. A candy thermometer helps indicate when the sugar is cooked to the right temperature. An old wire whisk can be cut open and used to capture the sugar strands to form the cotton candy.
