Real caramel sauce is a three-ingredient affair—nothing more than sugar, water, and cream. Okay, okay, salt and vanilla, too, but it hardly seems fair to count the seasonings. For a sweet and simple flavor, cook the sugar syrup until it's a pale, honey-colored hue. If you'd prefer a darker caramel with a slightly bitter edge, aim for a foxy amber hue. In either case, you're just 20 minutes away from the thick and gooey caramel sauce of your dreams.
