Lollipops, also known as suckers, are essentially hard candy with a short stick of some sort, which is either sucked or bitten until consumed. Lollipops come in a dizzying array of shapes and the ingredients used to produce lollipops vary depending on the manufacturer. Ingredients found in a lollipop without a special center include water, sugar, corn syrup, flavorings (natural and artificial), malic or citric acid.
