One day I was wondering how that sticky caramel stuff you can find in chocolate bars like Mars and Twix is made. With sugar, of course, and, why, let's add some cream. Though this recipe is quite simple - it only takes equal amounts of sugar and cream - it can be quite difficult to make this caramel sauce. It may take some practice to make caramel. I've made this sauce twice now, and it's been a great success.
