Taffy is a type of candy invented in the United States, made by stretching and/or pulling a sticky mass of a soft candy base, made of boiled sugar, butter, vegetable oil, flavorings, and colorings, until it becomes aerated, resulting in a light, fluffy and chewy candy. When this process is complete, the taffy is rolled, cut into small pieces and wrapped in wax paper to keep it soft. It is usually pastel-colored and fruit-flavored, but other flavors are common as well, including molasses and the "classic" (unflavored) taffy.

Candy, alternatively called sweets or lollies, is a confection that features sugar as a principal ingredient. The category, also called sugar confectionery, encompasses any sweet confection, including chocolate, chewing gum, and sugar candy. Vegetables, fruit, or nuts which have been glazed and coated with sugar are said to be candied.
