Caramel candy and caramel sauce contain the same ingredients. The difference between the two is the process of getting carbonized sugar and the amount of each ingredient used to achieve it. It's a science that requires paying extra attention to corn syrup, cream, and butter. You will need a separate recipe for caramel candies, as caramel sauce doesn't usually set up hard enough for candy. Although this recipe does not require a thermometer, if you ever try your hand at caramel candy, you're going to want to invest in one!
