What are the differences between caramel syrup and caramel sauce, and how do they each enhance the flavor of desserts?

Caramel syrup is thinner and more liquid than caramel sauce, which is thicker and creamier. Caramel syrup adds sweetness and a hint of caramel flavor to desserts, while caramel sauce provides a richer, more intense caramel taste and a smoother texture. Both enhance desserts by adding a sweet, buttery, and slightly bitter flavor that complements other ingredients like chocolate, fruits, or nuts.
